TL;DR: A comprehensive review of existing piezoelectric generators is presented in this paper, including impact coupled, resonant and human-based devices, including large scale discrete devices and wafer-scale integrated versions.

TL;DR: The development and implementation of an energy aware autonomous wireless condition monitoring sensor system (ACMS) powered by ambient vibrations that has been successfully demonstrated on an industrial air compressor and an office air conditioning unit, continuously monitoring vibration levels and thereby simulating a typical condition monitoring application.

TL;DR: The development of a self-powered system, specifically for sensor applications that can be energised on a test rig by an electromagnetic vibration-powered generator, that enables wireless operation without the use of a battery with a finite service life is detailed.

TL;DR: In this paper, a spray-coated fabric substrate with reduced surface roughness was used as the target substrate for the spray-covered fabric organic solar cells that contain multiple layers of electrodes and active materials.

TL;DR: In this paper, an accelerometer fabricated by a combination of screen printing and silicon micromachining is reported, achieving a sensitivity of 16 pC g-1, which compares very favourably with the sensitivity of 0.15 pCg-1 reported for thin-film devices, and highlights the need to further improve the mechanical properties and consistency of the PZT layer.
