Abstract

Human cardiovascular system represents an effective pumping mechanism that produces pulsations. Their energy can be picked up with the help of energy microharvesters. These are bioelectronic microdevices which transduce input energy into electrical power. This work focuses on hybridisation of piezoelectric effect and reverse electrowetting on dielectric phenomenon (REWOD). Mathematical modelling was used for the proposed energy harvester design validation. Piezoelectric harvester exciter was designed for investigation of different parameters such as chamber height, pulsation amplitude, piezoelectric disc diameter and material. Empirical data were compared to computational results. Hybrid harvester design recommendations were formulated.
