Three-phase piezoelectric composite for the gauge registration of arterial pulse waves

Features of three-phase piezoelectric composite development for artery pulsation wave registration detectors are considered. Piezoelectric composite is formed of polyvinyldenfluoride, epon resin and lead-zirconate-titanate class piezoceramic. It is shown, that composites with piezosensitive g33=0.10.35 Vm/N and elasticity module Е=(0.71.5)1010 N/m2 are efficient piezomaterials for development of registration detectors for artery pulsation wave.
