Fully Printed Piezoelectric Polymer Loudspeakers with Enhanced Acoustic Performance
Sandwich‐layer structures of poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)‐ poly(vinylidene fluoride‐trifluoroethylene) (P(VDF‐TrFE))‐PEDOT:PSS are fully printed on paper substrates. Dielectric spectroscopy demonstrates a fall‐off frequency of about 8 kHz. The P(VDF‐TrFE) layer is poled with a sufficiently high electric field.
