Analysis Of Output Voltage Profile Of Raindrop Impact Using Piezeolectric-Bridge Structure For Energy Harvesting

This research focuses on the output voltage profile generated from the piezoelectric-bridge structure for a single drop and continuous drop. In this study, a 5.6 mm of water droplet was used to impact the PVDF material (polyvinylidene fluoride) of 30 mm x 4 mm x 25 μm at different heights ranging fr...
