Resumo(s): | Energy harvesting devices allowing to recover wasted energy from the environment are increasingly developed. Mechanical energy is one of the most interesting sources of energy for energy harvesting and piezoelectric materials present excellent overall properties for the scavenging of that energy. Piezoelectric polymers and, in particular, polyvinylidene fluoride (PVDF), show appropriate mechanical properties for large amplitude movements, higher piezoelectric coefficients, transparency, and be easily integrated intro devices. A transparent piezoelectric energy harvesting device has been developed with screen printed transparent (72%) and conductive (42 Ω/sq) electrodes on PVDF sheets with a d33= -23 pC/N, generating about P~ 12 μW and P~ 8 μW under pressing and bending modes, corresponding to an energy per cycle of E~ 37 nJ and E~ 55 nJ, respectively. The piezoelectric energy harvesting characteristics of the materials was theoretical evaluated and the applicability of the materials for touch detection demonstrated. |
