Abstract
Described herein is a piezoelectric composite energy harvester (100) comprising a piezoelectric element (102) and an elastic cover layer (110). The piezoelectric element comprises a first electrode (104), a second electrode (106), and a piezoelectric layer (108) comprising a cross-linked silicone elastomer matrix and piezoelectric particles dispersed within the cross-linked silicone elastomer matrix. The elastic cover layer (110) is arranged to cover an outer side of the second electrode (106). The piezoelectric composite energy harvester is configured to bend, expand, contract, rotate, tilt, and/or move in all spatial directions.
Claims20
A piezoelectric composite energy harvester comprising:
- a piezoelectric element comprising piezoelectric layer disposed between a first electrode and a second electrode, wherein the piezoelectric layer comprises piezoelectric particles dispersed within a cross-linked silicone elastomer matrix;
- and
- an elastic cover layer contiguous with the second electrode, wherein the elastic cover layer is arranged so as to cover an outer side of the second electrode, wherein the elastic modulus of the elastic cover layer is less than the elastic modulus of the piezoelectric element,
- wherein the piezoelectric composite energy harvester is configured to bend, expand, contract, rotate, tilt, or move in all spatial directions.
A capacitive tire sensor comprising:
- a sensor module, the sensor module comprising an electric power source.
