Mechanical energy harvesting devices for low frequency applications: revisited

Abstract

With the advancement in low power system technology, energy harvesting systems have become a research hotspot over the last decade. The main advantage of the system is that they require minimum maintenance which makes them to be deployed in large scale or previously inaccessible locations. Therefore, the target of energy harvesting is to power autonomous electronic systems over their lifetime. Mechanical energy is the most ubiquitous and accessible energy source in the surroundings. Harvesting this type of energy exhibits a great potential for remote wireless sensing devices, charging batteries, and powering electronic devices. In this paper, we reviewed self-powered, self-sensing devices which describe different ways of mechanical energy harvesting. Comparison of mechanical energy harvesting devices in terms of their power output and frequency were presented. Self-powered system offers great potential for solving difficult problem of supplying energy
