摘要: Energy harvesting – the ability to gather energy from local environment power wireless devices has seen significant development over past decade as demand for portable electronics increases. Although on-board batteries provide a simple means of providing these devices, their density can be insufficient miniature or long-term deployment (Anton & Sodano, 2007). A replenishing onboard storage potential reduce frequency battery replacement eliminate need altogether. Vibration-based in particular garnered much attention due ubiquity vibrational (Roundy et al., 2003). Several methods electromechanical transduction vibrations have been investigated, including electromagnetic induction, electrostatic varactance, and piezoelectric effect, latter being province this chapter.
