State of the Art

One of the most important global problems of our time is that limited natural resources cannot meet the increasing energy needs. Most of these resources are made up of fossil fuels and used by generating electrical energy from these sources, while thermoelectric energy generators can be used to increase energy efficiency by recycling the heat energy released.

Thermoelectric power generators are devices which directly convert temperature difference into electrical energy by the thermoelectric effect, the efficiency of which is between 5-8%. When the temperature difference occurs on each side of a thermoelectric device, there occurs voltage or, on the contrary, a voltage difference occurs when voltage is applied to a device. The temperature gradient applied in the atomic dimension causes the loads in the material to spread from the hot side to the cold side. This effect is used in electricity generation, temperature measurement or to change the temperature of the material. The use of thermoelectric devices in temperature control is common due to the temperature and cold direction determined by the pole of the applied voltage. An example of a thermoelectric device in the literature is US2017/033272. Said document relates to a method to make a flexible thermoelectric generator device and related devices. Each thermoelectric couple in said thermoelectric generator device may comprise first and second columns of respective first and second conductivity types. The thermoelectric generator device comprises first and second terminals coupled to the plurality of bottom contacts and further comprise thermoelectric material. The thermoelectric generator device according to the invention is only intended to generate electricity from the temperature difference. Therefore, the usage areas are limited. Consequently, the existence of the above problems and the inadequacy of the available solutions made it necessary to make improvements in the relevant technical field.

A. Flexible hybrid nanogenerator H. Pipeline Detailed Description of the Invention

In this detailed description, preferred alternatives to the flexible hybrid nanogenerator (A) according to the invention are explained only for a better understanding of the subject matter with no limiting effect.

Figure 1 is an overview of the flexible hybrid nanogenerator (A) of the present invention. Accordingly, the flexible hybrid nanogenerator (A) basically comprises a full or semicircular flexible material (10) such as fabric, rubber which holds the whole structure together and provides ease of assembly, a thermoelectric material (20) which is located on said flexible material (10) and generates electrical energy from the temperature difference by means of the cooling fin (21 ), a electromagnetic material (30) which is located on said flexible material (10) and generates electrical energy from vibration and motion energy, an electronic board (40) which converts the generated electrical energy into AC/DC or DC/AC current and thereby brings it to the desired voltage, a lithium polymer battery (50) which is located on said flexible material (10) and which stores the generated electrical energy, a charging module (60) which is located on said flexible material (10) and which enables any device to be charged wirelessly.

The flexible material (10) is a material such as fabric, rubber, which holds the whole structure forming the flexible hybrid nanogenerator (A) together.

Said flexible material provides ease of installation in the industrial field, for example, in a pipeline (H), in the exhaust of an electric automobile, or in human/animal wrist for personal use.

The amount of heat that the material receives from the surface increases with good adhesion to said surface, and thus the energy produced is proportionally increased.

The thermoelectric material (20) on the flexible material (10) generates electrical energy from the temperature difference by means of the cooling fin (21 ). Said thermoelectric material (20) comprises Boron Nitride or Graphene Nitride.

The electromagnetic material (30) comprises a current-producing neodymium magnet (31 ), a copper wire (32) which generates energy from the current generated by said neodymium magnet (31 ), and a teflon cylinder (33) on which said neodymium magnet (31 ) and said copper wire (32) are connected for generating electrical energy from vibration and motion energy. Said teflon cylinder (33) ensures that the neodymium magnet (31 ) cannot move easily and the friction is low.

The electronic board (40) is connected with thermoelectric material (20) and electromagnetic material (30) and converts the generated electrical energy into AC/DC or DC/AC current, bringing it to the desired voltage. Said electronic board (40) is also connected with a lithium polymer battery (50). The lithium polymer battery (50) provides storage of the generated electrical energy. At the same time, a super capacitor connected to the lithium polymer battery (50) may be placed next to the lithium polymer battery (50) to provide storage of electrical energy.

There is a charging module (60) which is on the flexible material (10) and associated with the electronic board (40) and the lithium polymer battery (50). The charging module (60) enables any device to be charged wirelessly.

The flexible hybrid nanogenerator (A) is suitable for use in all areas where energy is needed and where energy is not available. The flexible hybrid nanogenerator (A) is used by being attached to the wrist of a human or animal body in personal use and by covering the whole surface of equipment in the use of industrial field.

The flexible hybrid nanogenerator (A), by means of thermoelectric material (20) contained therein, generates electrical energy - depending on where it is used- for example, from the waste heat received from the equipment if it is used on a pipeline (H) as an industrial equipment as shown in Figure 2, or from the heat received from the body if it is used in a human/animal body.

On the other hand, the electromagnetic material (30) generates electrical energy from vibration and motion energy. The electrical energy generated by thermoelectric material (20) and electromagnetic material (30) is converted to AC/DC or DC/AC current by means of electronic board (40), brought to the desired voltage, and stored in the lithium polymer battery (50). The electrical energy stored in the lithium polymer battery (50) meets the electrical needs of any device by means of the charging module (60).

While the flexible hybrid nanogenerator (A) can generate electrical energy from the temperature difference via thermoelectric material (20) and at the same time from vibration and motion energy by electromagnetic material (30), in an alternative embodiment of the invention, it can generate electrical energy from vibration and motion energy only by using electromagnetic material (30). In this way, it can be designed such as to contain electromagnetic material (30) only in areas having vibration and motion energy, thus reducing the cost.

In an alternative embodiment of the invention, it may also be in the form of a heat shield capable of generating electricity from flexible hybrid nanogenerators (A) which can be used in automotive and industry, or flexible tubing capable of generating electricity as hot or cold fluid passes through it.
