Energy harvesting for infrastructure sensing systems

J.T. Scruggs,    University of Michigan, USA

Abstract:

This chapter gives an overview of some of the fundamental design issues arising in vibration energy harvesting systems for sensing applications. We focus primarily on piezoelectric and electromagnetic transducers. Linear dynamical models for these systems are presented and discussed. Impedance matching theory is discussed, and its application to monochromatic energy harvesting is explained. Fundamental limits on power generation are presented for monochromatic disturbances, and analogous limits for stochastic disturbances are briefly presented. Passive tuning techniques are discussed, for reactive power compensation.

A number of basic ...
