Piezoelectric energy production

The concept of piezoelectric energy production is based on energy harvesting devices using as generation materials single crystals, ceramics, polymers and composites. These production systems can harvest wasted environmental energy and convert it essentially into electrical energy. There are different nano- and micro-scale power harvesters which are increasingly useful for powering mobile electronics and low power devices, even in hardly accessible areas. Despite many efforts in the development of new materials, the most widely used materials in device applications remain the ceramics of the PZT family, since they still present the higher output performances in the range of mW of generated power.The authors thank Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UID/FIS/04650/2013 (POCI-01-0145-FEDER-006941) funded by national funds through Fundação para a Ciência e a Tecnologia (FCT) and by FEDER funds through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI).
