Abstract
Supplying electrical energy to wireless sensors nodes from alternative sources can increase the reliability of the sensing and measurement systems. Mechanical vibrations available in the environment provides a viable source of energy to supply electrical power to sensor nodes. Micro-energy harvesting systems are discussed in this article, which can significantly benefit wearable and implantable sensors. Three commonly used energy conversion mechanisms including electromagnetic, piezoelectric and capacitive transducers are briefly introduced, and recently proposed methods to improve the efficiency of these harvesters in micro-dimensions are discussed in more detail.
