Abstract

Here, in this present work, the developmentof a lightweight, flexiblehybrid energy harvester using a composite BaTi0.89Sn0.11O3 (BTS)/polydimethylsiloxane (PDMS) has beenproposed. A significantly enhanced output performance of hybrid energyharvester (HEH) was achieved by strategically coupling the piezoelectriceffect with the triboelectric output. Thus, multiphase coexisted BTSparticles as confirmed by the structural and dielectric properties,with a high value of d (33) coefficient & SIM;412pC/N, were used as filler for the functional layer (PDMS) of the device.The hybrid energy harvesting device can harvest a maximum voltageof & SIM;358 V with an instantaneous power density of 1.08 mW/cm(2) from human finger imparting (force & SIM; 100 N, frequency & SIM; 4 Hz). The fabricated device harvests energy from handwritingand differentiates fine patterns of different letters by using itas a writing pad. In addition to that, a wireless system utilizingan inductor-based resonant coupling mechanism was developed for wirelesspower transmission. The easy processability, flexibility, high outputperformance, and alignment toward a power source for wireless powertransmission make the fabricated HEH device a promising candidatefor various applications for portable smart flexi-electronics.
