Evaluation and Verification of Energy Recovery for Piezoelectric Vibration

In order to improve piezoelectric power generation capacity, the evaluation and verification of energy recovery model were established, to explore the effects of vibrators structure, material properties, masses quality, and vibration environment on the piezoelectric vibrators. Piezoelectric vibrators were made up of piezoelectric ceramics, mass blocks, and metal substrates. Then experiment to verify the correctness of the model. The results show that the vibrators will get large generation under random vibration with a vibration frequency of 25 Hz–125 Hz. In this vibration environment, the performance of beryllium copper in several copper-based materials with the same thickness is optimal. The power generation capacity of the mass above 30 g is basically stable at 1 mW, and there are different power generation on the different thickness (0.25 mmhe 0.2 mm) with the same material.
