Title:
PRESSURE SENSOR AND COMPOSITE ELEMENT HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2017/078335
Kind Code:
A1
Abstract:
The present invention provides a pressure sensor and a composite element having the same, the pressure sensor comprising: a first and a second electrode layer that respectively have first electrodes and second electrodes arranged spaced apart and facing each other; and a piezoelectric layer that is arranged between the first and the second electrode layer, wherein the piezoelectric layer includes a plurality of piezoelectric bodies having a plate shape arranged in a polymer. In addition, the plurality of piezoelectric bodies are arranged in one direction and the other direction crossing each other in the horizontal direction, and in the vertical direction. By using a piezoelectric body having a plate shape, the present invention exhibits excellent piezoelectric properties compared to existing piezoelectric powders, and as a result can easily sense even a minute pressure thereby improving sensing efficiency.
