| Abstract: | Summary The piezoelectric strain coefficient d13 of stretched and unstretched acrylonitrile/methylacrylate copolymer films has been investigated as a function of poling conditions. The maximtun d31 values obtained for stretched and unstretched films were around 3 and 0.85 pC/N, respectively. The time stability of piezoelectricity is relatively low. |
