Piezoelectric based V-shape cantilever beam design of energy harvester for biomedical applications

Abstract This research paper exhibits the design of a V-shaped cantilever beam as micro Energy Harvester (EH) having Piezoelectric (PZT) its energy source for biomedical applications. PZT based materials have ability to convert mechanical into electrical energy. Low-power devices mostly operate using (i.e. batteries). But batteries are treated bio-hazard due massive use To overcome this toxic bio-hazard, proposed EH can solve limitations. perform experimental work, parameters - length, width and thickness been considered simulated COMSOL Multiphysics get resonant frequency 156.19 Hz which is lower than previous work. It was observed that obtained be converted AC voltage (mV) material. output DC voltage, circuit an Ultra-Low-Power (ULP) will designed in LTSPICE software. Finally, integration both V-shape ULP implemented PCB hardware generate power (10 µW), stored super-capacitor devices-pacemaker.
