Title:
CAPACITANCE CHANGE TYPE ELECTRIC POWER GENERATING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/108192
Kind Code:
A1
Abstract:
[Problem] To obtain a capacitance change type electric power generating element which has high power generation efficiency.
[Solution] An electric power generating element (1) has a configuration that is provided with: a composite layer (12) that is obtained by dispersing ferroelectric particles (11) in a dielectric elastomer (10); and a pair of electrodes (21, 22) that are arranged above and below the composite layer (12) and expand and contract in response to expansion and contraction of the composite layer. In this connection, the ferroelectric particles (11) have crystal orientation and are orientationally dispersed in the dielectric elastomer (10). The ferroelectric particles (11) are polarized in the layer thickness direction of the composite layer (12).
