Design and Experimental Study of Novel Piezoelectric Vibration Energy Impact Mass Harvester

Electricity is the greatest crisis in the world on one side and another side is environmental pollution is caused by E-waste especially due to smart devices such as mobile phones, laptops, compact devices, computer spare parts, unrecyclicable batteries etc. By considering these problems authors are taken up a research on energy harvesting by using ambient vibrations. In this field so far people had done a lot of research only by using clamp-free beam with tip mass for dynamic flexibility. In this paper the authors are demonstrating a novel piezoelectric vibration energy impact mass harvester (NPVEIMH) by using lead ball as impact mass for optimising the output power. Here impact mass harvester is fulfilling the purpose of generating electricity maximum. The impact mass of 5 grams lead material is considered as a hitting mass on Lead Zirconate Titanate(PZT) patch and developed a power of 9.072W as an output at the resonance frequency of 177.143 kHz for charging the low power devices for impulse power applications.
