A tuning element based on piezoelectricity and a resonator provided with such a member.
Provided is an oriented piezoelectric ceramic of satisfactory piezoelectricity, which includes a metal oxide represented by (l-x)NaNbO3-xBaTiO3.
Disclosed is a piezoelectric sheet composed of a polylactic acid sheet and capable of exhibiting a high piezoelectricity in the thickness direction.
Each substructure comprises a flatness regulation layer (3041), a piezoelectricity sensing layer (3042), and a surface adsorption layer (3044).
The oxide layer (14) is also good in dielectric constant, piezoelectricity and electrostrictivity since the direction in which a voltage is applied is consistent with the polarization axis.
Disclosed is an organic piezoelectric material which has particularly excellent heat resistance, while exhibiting excellent transparency, surface gloss, adhesion and piezoelectric characteristics.
The measuring pad comprises a film having piezo and/or pyro electrical characteristics, for example a PVF-film (Poly Vinyl Fluoride), or any other sensor having similar properties.
The system is implemented as storage "satellite" container/housing/carrier unit for piezoelectric power generator, power storage and spare volume for transported cardio stimulator devices.
