Summary

An autonomous system is composed of several parts, including the energy harvester, sensing, computing and communications subsystems. Basically, the energy from the harvester must stored in a capacitor or battery, before being used by the system. This implies electrical circuitry optimization, but in this chapter only the harvester is considered. After a brief review of MEMS vibrational energy harvesting concepts and piezoelectric materials, the chapter presents the most studied piezoelectric nanoscale materials and the various integration techniques. These aspects are discussed from a theoretical point of view, using simple scaling rules, and are followed by a discussion of the state-of-the-art and of the prospects of nanostructure-based mechanical energy harvesters. Then, the chapter presents the possibility of combining mechanical harvesting with to other techniques (like solar), leading to a multisource scheme.
