the development of energy harvesters and sensors. Among the piezoelectric materials, special attention has been paid to electroactive polymers such as poly(vinylidene fluoride) (PVDF) and its copolymer poly(vinylidenefluoride-co-trifluoroethylene) (PVDF-TrFe), which is one of the most extensively

In the last years, innovative energy harvesting systems based on the piezoelectric effect, able to convert vibrational mechanical energy
fluoride-co-trifluoroethylene) (PVDF-TrFE) [15][16][17]. This copolymer shows a higher piezoelectric coefficient than PVDF, while still maintaining a high flexibility, sensitivity, and mechanical durability. It is also, like PVDF, a biocompatible polymer.
