Piezoelectric PVDF-TrFE/PET Energy Harvesters for Structural Health Monitoring (SHM) Applications

This study presents a piezoelectric energy harvester made of poly(vinylidene fluoride-trifluoroethylene)/polyethylene terephthalate for use in structural health monitoring applications. The piezoelectric energy harvester was made of a layer of polyvinylidene fluoride-trifluoroethylene (PVDF/TrFE). In addition, PET sheets, double-sided micron-thick tapes, and PVDF-TrFE sheets were utilized in the fabrication of the device. The proposed device was characterized by measuring its output voltage and current. The output power of the harvester was sufficient to operate a MEMS pressure sensor under wind pressure, with a maximum current of 291.34 mu A and a maximum voltage of 937.01 mV. The power value obtained was 272.99 mu W.
