Description:
PIEZO CRYSTAL FOR ANULTRASONIC TRANSDUCER

TECHNICAL FIELD

[0001] The present disclosure relates generally to generation and focusing of energy waves in general, e.g., sonic waves and ultrasound waves, and particularly to Piezo crystal of an ultrasonic transducer, useful in medical treatments, such as but not limited to, stimulation of cell metabolism, and other non-medical uses, such as but not limited to, non-destructive testing of structures, capable of generating energy waves having multiple resonant frequencies.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Researches indicate that cells/organs/living organisms respond to internal as well as external surroundings. It has been observed that a slight change in pH levels within a cell can actuate a certain protein synthesis and can halt another for the same function. For example, a carcinogen is needed to trigger a change in behaviour of a healthy cell and make the cell start expressing proteins which turn the cells cancerous. If an unhealthy change in environment can alter the state of a cell, then the converse should be true too. A healthy environment should trigger a healthy change.

[0004] Autonomic nervous system (ANS) in human beings is a control system that acts largely unconsciously and regulates bodily functions such as heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal to name a few. Humans do not have much control over their heart rate or breathing. However, a soothing melody lowers our heart rate, hearing a loud explosion leads to higher heart palpitations. Such bodily functions are governed by the ANS through cells and organs present throughout body of a human being.

[0005] It has been profoundly envisaged that sound and vibrations bypass the conscious mind and have a direct effect on the ANS, thus, releasing regulatory hormones and enzymes and changing internal as well as external environment of various cells and organs. It is also a well researched fact that every healthy living organism/cell resonates within a defined frequency range. Also, for unhealthy/sick cells the defined frequency range changes that leads to losing of desired vibrancy and vitality of the unheal thy/sick cells. Further, imposing external electromagnetic stimulation like radio waves disturbs vibrancy and vitality of healthy cells, impacts its resonance and eventually causing cell lysis, a medical condition that refers to the breaking down of membrane of a cell, often by viral, enzymic, or osmotic mechanisms that compromise integrity of the cell.

[0006] Ultrasonic which is routinely used for diagnostic applications throughout the world is now being adopted in various fields of drug delivery systems and other therapeutic use. Interactions of acoustic ultrasonic with biological tissues play an important role in biomedical applications of ultrasonic. Low intensity ultrasonic is known to permeate the skin, modulate the cell membrane and alter its properties possibly activating signal transduction pathways. The energy absorbed by the enzymes from the ultrasonic effects the overall function of the cell.

[0007] Currently available ultrasonic transducers to stimulate cell metabolism typically incorporate a quartz crystal that deform in response to high frequency signals applied to them in the form of electrical voltage, thereby leading to generation of ultrasonic waves. However, such ultrasonic transducers are primarily based around a single resonant frequency and do not provide for generation of resonant frequencies spanning over various energy wave ranges.

[0008] There is therefore a need in the art to provide a Piezo crystal for an ultrasonic transducer capable of generating energy waves having multiple resonant frequencies spanning over various energy wave ranges.

[0009] As used in the description herein and throughout the claims that follow, the meaning of“a,”“an,” and“the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of“in” includes“in” and“on” unless the context clearly dictates otherwise.

[0010] In some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0011] The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g.“such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.

[0012] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all groups used in the appended claims.

[0036] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

[0037] Embodiment explained herein relates to a Piezo crystal (also referred to as Piezoelectric transducer, Piezoelectric crystal and Piezoelectric plate hereinafter) of an ultrasonic transducer, useful in medical as well as non-medical applications, said Piezo crystal capable of generating energy waves having multiple resonant frequencies, and said ultrasonic transducer capable of generating as well as shaping the energy waves in order to generate ultrasonic vibration by converting an oscillating electric field applied to the Piezo crystal into ultrasonic vibration.

[0038] An aspect of the present disclosure pertains to a Piezo crystal for an ultrasonic transducer to generate multiple resonant frequencies spanning over defined sonic and ultrasound ranges, said Piezo crystal including a metal substrate disc coupled with a crystal compound disc having a dead zone region at its centre, said Piezo crystal capable of generating a primary wavefront, wherein the Piezo crystal has a flat band response for all the resonant frequencies, and wherein the primary wavefront generated thereof includes low frequency ultrasound waves with encapsulated sonic waves.

[0039] In an embodiment, the Piezo crystal covers a broad coverage of the defined sonic and ultrasound ranges. In an embodiment, resonant ultrasonic frequency of the Piezo crystal ranges between 20 kHz to 100 kHz. In an embodiment, resonant sonic frequency of the Piezo crystal ranges between 1.5 Hz to 20 kHz.

[0040] In an embodiment, the metal substrate disc is arranged concentrically with the crystal compound disc.

[0041] In an embodiment, the ultrasonic transducer includes a cavity resonator to shape the primary wavefront in order to obtain multi frequency sweeping primary standing waves. In an embodiment, the cavity resonator compensates for resonant frequency tolerances of the Piezo crystal.

[0042] In an embodiment, the primary wavefront passes through a secondary wave shaping and scattering unit that attenuates and shapes the primary wavefront to obtain a secondary wavefront. In an embodiment, the secondary wave shaping and scattering unit includes a wave sheer grill that scatters the secondary wavefront as to convert the secondary wavefront into multi-direction energy waves. In an embodiment, the wave sheer grill slices the energy waves at appropriate grill angles.

[0043] In an embodiment, the wave generating device emits the multi-direction energy waves that includes multi-directional low frequency ultrasound carrier sweep with an encapsulated multi-directional sonic frequency sweep having frequency ranges that covers natural resonant frequency range of human body as a whole as well as at cellular level.

[0044] FIG. 1 illustrates an exemplary perspective view of proposed Piezo crystal 100 for a wave generating device (also referred to as ultrasonic transducer hereinafter) in accordance with an embodiment of the present disclosure. In an aspect, the Piezo crystal 100 includes a metal substrate disc 102 arranged concentrically with a crystal compound disc 104 that contains a crystal elements, such as, quartz, Rochelle salt and other ceramic as well as non-ceramic materials. The crystal compound disc 104 includes a dead zone region 106 at its centre for creating hollowed cylindrical wavefronts. The metal substrate disc 102 can be coupled with the crystal compound disc 102 by a fastening technique, such as, adhesion, welding, fitting and the likes.

[0045] In an aspect, the dead zone region 106 assists the Piezoelectric crystal 100 to generate a primary wavefront that includes low frequency ultrasound waves with encapsulated sonic waves. In an embodiment, resonant ultrasonic frequency of the Piezo crystal 100 can range between 20 kHz to 100 kHz. In an embodiment, resonant sonic frequency of the Piezo crystal 100 can range between 1.5 Hz to 20 kHz.

[0046] In an embodiment, shape of the crystal compound disc 104 assists in generation of a plane ultrasonic wave. However, it would be appreciated that crystal compound disc of a different shape such as a crystal disc having a curve on its radiating surface can be used to generate a slightly concave or bowl shape ultrasonic wave that can focus/converge at a specific point.

[0047] In an embodiment, the Piezo plate 100 covers a broad coverage of the defined sonic and ultrasound ranges. In an embodiment, the Piezo crystal 100 has a flat band response for all the resonant frequencies.

[0048] In an embodiment, the Piezo plate 100 is configured to generate multi -frequency resonant waves such that the resonant waves encompass multiple desired frequencies. Special doping techniques are implemented and various compounds in correct proportions are used in formulation of the crystal compound disc 104. In a way, the crystal compound disc 104 is a combination of many single frequency crystals into one.

[0049] Referring now to FIGs. 2A and 2B, where front view and sectional view of a section A-A of the Piezo crystal 100 is shown, diameter of the metal substrate disc 102 can range between 27 mm to 40 mm. In an embodiment, diameter of the crystal compound disc 104 can range between 20 mm to 30 mm. In an embodiment, diameter of the dead zone region 106 can range between 3.5 mm to 6 mm. In an embodiment, thickness of the metal substrate disc 102 can range between 0.25 mm to 0.5 mm.

[0050] In an embodiment, primary capacitance range of the Piezo crystal 100 can be in the range of 18 nF to 31 nF. In an embodiment, feedback capacitance range of the Piezo crystal 100 can be in the range of 2.8 nF to 6.7 nF.

[0051] In an embodiment, the primary wavefront can pass through a secondary wave shaping and scattering unit (not shown) that attenuates and shapes the primary standing waves to obtain a secondary wavefront. In an embodiment, the secondary wave shaping and scattering unit can include a wave sheer grill (not shown) that can scatter the secondary wavefront as to convert the secondary wavefront into multi-beam and multi-direction energy waves. In an embodiment, the secondary standing waves get emitted from the secondary wave shaping and scattering unit in the form of an energy wavefront and propagates forward to induce vibratory impulses into a human body or a material located in front of the secondary wave shaping and scattering unit. In an embodiment, the wave sheer grill can slice the energy waves at appropriate grill angles.

[0052] FIG. 3A illustrates an exemplary side view of the ultrasonic transducer with a visual representation of energy wavefront as it propagates forward in accordance with an embodiment of the present disclosure. FIG. 3B illustrates an exemplary perspective view of the ultrasonic transducer with a visual representation of energy wavefront 302 as it propagates forward in accordance with an embodiment of the present disclosure. In an embodiment, the wave generating device 300 can include a cavity resonator to shape the primary wavefront in order to obtain multi frequency sweeping primary standing waves.

[0053] In an embodiment, a cavity resonator (not shown) can shape the primary wavefront generated by the Piezo crystal 100 as to obtain multi frequency sweeping primary standing waves. The cavity resonator can compensate for any resonant frequency tolerances of the Piezo crystal 100.

[0054] In an embodiment, the primary standing waves are generated as a result of interaction of the emitted waves and reflected waves between the cavity resonator and the Piezo crystal 100. The Piezo crystal 100 is the primary source emitting the primary wavefront that are tuned inside the cavity resonant to generate the primary standing waves. The primary standing waves as they traverse through the secondary wave shaping and scattering unit create secondary standing waves. This interaction and cross talk produces a wavefront which is sliced at appropriate angles at the wave sheer grill, thereby generating a multi-directional energy wavefront capable of engulfing a subject being treated by the wave generating device from all directions.

[0055] In an embodiment, the ultrasonic transducer includes a secondary wave shaping and scattering unit that can attenuate and shape the primary standing waves to obtain a secondary wavefront. In an embodiment, the secondary wave shaping and scattering unit can include a wave sheer grill that can scatter the secondary wavefront as to convert the secondary wavefront into multi-direction energy waves that are in the form of the donut shaped/toroidal energy wavefront 302. In an embodiment, the wave sheer grill can slice the donut shaped/toroidal energy waves at appropriate grill angles.

[0056] In an embodiment, the wave generating device 300 emits the multi -beam and multi-direction donut shaped/toroidal energy wavefront 302 that includes multi-directional low frequency ultrasound carrier sweep with an encapsulated multi-directional sonic frequency sweep having frequency ranges that covers natural resonant frequency range of human body as a whole as well as at cellular level in order to effective stimulate and/or module cell metabolism of the human body.

[0057] It would be appreciated that the primary wavefront generated by the proposed Piezo crystal 100 can be used for medical as well as non-medical applications, for example, for non-destructive testing of various materials that utilizes energy waves, such as ultrasound waves and sonic waves, to detect defects and/or anomalies in the materials.

[0058] FIG. 4 illustrates an exemplary representation of the donut shaped/toroidal energy wavefront emitted from the ultrasonic transducer in accordance with an embodiment of the present disclosure. In an aspect, the donut shaped/toroidal energy wavefront 302 includes multi-directional low frequency ultrasound carrier sweep with an encapsulated multi directional sonic frequency sweep. The sonic waves are encapsulated with the ultrasound waves such that frequency ranges of the ultrasound waves and the encapsulated sonic waves can confer with the natural resonant frequency of human body as a whole as well as at cellular level in order to effective stimulate and/or module cell metabolism of the human body with the help of the ultrasonic vibrations generated thereof.

[0059] In an embodiment, sonic waves are beneficial in stimulating bodily functions at organ and cell level. However, use of sonic waves in medical applications is confined as they do not have the ability to penetrate deep tissue. On the contrary, low intensity and low frequency ultrasound waves have deeper penetration than sonic waves. Hence, encapsulation of sonic waves with ultrasound carrier allows the sonic waves to piggy back on the ultrasound carrier. In addition, the ultrasound carrier also assists in cellular/organ revitalization to enhance operational capability of the medical application, for example, engulfing a subject being treated with the generated donut shaped/toroidal energy waves from all directions.

[0060] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms“comprises” and“comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C ....and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc. The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the appended claims.

The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
