Abstract

Negative capacitance can lead to advantages in piezoelectric based passive vibration suppression system using inductive shunting. However, the optimal amplifier (op-amp) as the key component in the negative capacitance circuit consumes power, leading to additional power requirements to operate the system. In this research, we explore the development of a self-powered circuitry that integrates together inductive shunting for vibration suppression, piezoelectric energy harvesting, and negative capacitance. With careful analysis of the power consumption of negative capacitance, the output power of energy harvesting system, and the vibration suppression performance, we can identify a circuitry design that can take advantage of negative capacitance to enhance vibration suppression performance where the net power of the system remains to be positive. Our results are validated through experimental investigations.
