Description
Micro energy harvesting is the conversion of ambient energy, such as body warmth or machine vibration, into electric energy to locally power embedded, small-scale devices such as wireless personal health-monitoring systems or environmental sensors, making them independent of rapidly exhausted batteries or location restricted power grids. Enabling this unprecedented level of autonomy, particularly at the micro-scale, requires innovation in harvesting devices, power management circuits, and complete system design, in order to ensure the desired functionality and reliability of the respective device even if the supply of ambient energy varies with time.

This book addresses a wide range of aspects of energy harvesting at the micro-scale, with a focus on miniaturized and micro-fabricated devices. It provides an overview of the field by compiling knowledge on design, materials development, device realization and aspects of system integration. The book covers emerging technologies such as nanotechnology-based materials and harvesters, as well as applications in power management, energy storage, medical applications and low-power system electronics. In addition, it surveys the energy harvesting principles being developed at the micro-scale based on chemical, thermal, mechanical as well as hybrid and nanotechnology approaches.
