Self-powered Sensing for Chemical and Environmental Detection

2016
In this chapter, we present self-powered chemical/environmental sensors, the working principle of which relies on the changeof triboelectric charge density when the pretreated triboelectric surface has been assembled with certain chemical species, usually by immersing it in the aqueous solution of chemicals.

Self-powered Sensing for Tracking Moving Objects

2016
Under mechanical triggering, TENGs canproduce electrical signal even without applying a power source, which can be used as sensors for detecting a moving object. This chapter reviews some of the existing studies in the TENG sensors to sense displacement, rotation, velocity, and acceleration. Their working principle, design, performance and applications

Self-powered Sensing for Human-Machine Interface

2016
In this chapter, we discussed the first type of pressure/touch sensor based on TENG. In general, the pressure response contains a high sensitivity region at relatively low pressure, and a low sensitivity region at higher pressure. Possible explanations of this behavior include full closing of air gap or saturation of increasing contact area between the

Simultaneous Triboelectric and Mechanoluminescence Sensing Toward Self‐Powered Applications

Advanced Sustainable Systems
AbstractSimultaneous phenomena of triboelectricity and mechanoluminescence (ML) acquire vital insights into the mechanics of charge separation and recombination, as well as the relationship between mechanical stress and light emission. In the present work, polydimethylsiloxane (PDMS) and ZnS:Cu particle‐based composites are fabricated, which have good ...
