Abstract
PURPOSE: To improve the piezo-electric characteristic by employing micro particle in specific grain size range as ferro-dielectric celamic micro particle while fluorine rubber as macromolecule material.
CONSTITUTION: Fluorine rubber or macromolecule containing fluorine rubber is mixed with piezoelectric micro particle composed of ferrodielectric celamic of such grain size as passes through sieve of 210μ nominal size and remains more than 90 wt% over 44μ sieve. Then it is molded and fixed with electrodes and while heating in a constant temperature tank DC voltage is applied to perform polarization. Consequently flexible piezoelectric matrial having excellent piezoelectric characteristic where the flexibility isn't deteriorated even when the max. filling amount of micro particle is increased can be obtained. While when increasing the permitivity the performance as dielectric material can be improved.
