[...] In 1969, strong piezoelectricity was observed in PVDF, with the piezoelectric coefficient of poled (placed under a strong electric field to induce a net dipole moment) thin films as large as 6–7 pC/N: 10 times larger than that observed in any other polymer.[4]" (Also apparently has applications in the manufacture of supercapacitors, but that's a tangential discussion...) https://www.google.com/search?q=polymer+transducer https://www.google.com/search?q=polymer+transducer https://en.wikipedia.org/wiki/Transducer https://en.wikipedia.org/wiki/Transducer
