Piezo polymer films are beginning to create a major impact on product design after its initial discovery in 1969. The material's predecessor, polyvinylidene fluoride (PVDF) film, was discovered to exhibit piezoelectric activity in 1969 but was not given much laboratory research. However, the mass production of PVDF films saw its emergence in applications including toys, shoes, disk drives and ultrasonic devices., Polymer-film sensors may be the solution for gauging motion or temperature changes without spending a lot of money or taking up much space. Industry analysts say it takes about 25 [...]
