Stretchable triboelectric nanogenerator with exteroception-visualized multifunctionality

Abstract

Stretchable photoelectric devices combining mechano- and thermo-chromic liquid crystals (LCs) with triboelectric nanogenerator (TENG) assembly are showing great application prospects as wearable biomotion energy harvester and optically visualized, multifunctional sensors...

A stretchable and adhesive composite hydrogel containing PEDOT:PSS for wide-range and precise motion sensing and electromagnetic interference shielding and as a triboelectric nanogenerator

“…[35][36][37][38][39][40][41][42][43][44][45][46][47][48] Moreover, as an important conductor, the conductive hydrogel with flexibility and adhesion is an ideal candidate for TENG soft electrodes. [49][50][51][52][53][54] For example, Hang, Kong and Hao et al designed a hydrophobic, icephobic and ultrafast self-healing TENG with outstanding thermal-resistant, non-drying and nonfreezing properties. 55 This novel TENG showed excellent electrical output and stability in a wide temperature range.…”

Cellulose Gel Mechanoreceptors – Principles, Applications and Prospects

“…enticing candidate as artificial electronic skin (e-skin), and wearable smart sport assistant devices such as bench pressing training (Figure 6c), [208] table tennis training, [4] and basketball training, [57] etc. Another distinctive ability by gel sensor arrays refers to anisotropic sensing achieved via weaving two piezoresistive ionogel fibers into ordinary soft fabrics along the warp and weft directions (Figure 6d).…”

“…While an array of gel sensors displays the capability of detecting the location and pressure of touch [ 1 ] and even diverse stimuli such as vibration, humidity, and temperature ( Figure a), [ 207 ] a multipixel HPC hydrogel skin can perceive subtle movements of the muscles by displaying dynamic responses with spatiotemporal signal distributions (Figure 6b). [ 84 ] Such space‐intensity real‐time multisensory detection of gel sensor macro‐ and micro‐arrays makes them enticing candidate as artificial electronic skin (e‐skin), and wearable smart sport assistant devices such as bench pressing training (Figure 6c), [ 208 ] table tennis training, [ 4 ] and basketball training, [ 57 ] etc.…”
