A stretchable piezoelectric elastic composite

In this work, a stretchable piezoelectric elastic composite has been developed by incorporating PbZr0.52Ti0.48O3 (PZT) particles into polymer matrix. The output voltage and current can reach 8 V and 0.4 μA, respectively. Likewise, the steady piezoelectric signal can respond to different strain rates. The measurement on human body shows that the piezoelectric composite can be used to capture kinetic energy and monitor limb motion for body sensor network application. This work is significant for the conformal assembly of piezoelectric devices used in artificial intelligence system.
