An extreme condition-resistant superelastic silica nanofiber/MXene composite aerogel for synchronous sensing and thermal management

“…In recent years, wearable sensors have attracted extensive attention in health monitoring, 72 disease diagnosis, 8 and motion detection. 7 With the ideal combination of high elasticity, excellent fatigue resistance, and wide pressure detection range, SMA30 was assembled as a wearable sensor to detect various human motions in real time.…”

“…Specically, pressure sensors that can convert received forces into electrical signals are widely used in wearable electronics, clinical diagnosis, new energy industries, and deep space exploration. Based on different working mechanisms, pressure sensors are mainly divided into piezoresistive, 1,2 piezoelectric, 3,4 capacitive, 5,6 and triboelectric, 7,8 among which the piezoresistive sensors have been extensively studied and widely used due to their merits of the broad selection of active materials, easy integration, excellent stability, high sensitivity and precision, and convenient signal collection. Aerogels, porous materials with a threedimensional (3D) connected network structure, have recently been investigated as ideal active materials for piezoresistive sensors due to their low density and high porosity.…”

Triboelectric-induced ion mobility for artificial intelligence-enhanced mid-infrared gas spectroscopy

“…Therefore, plasma-enhanced infrared absorption spectroscopy enables the ultrasensitive detection of molecules with the aid of an existing high-voltage power source (ion mobility). Secondly, regarding ion mobility, a triboelectric nanogenerator 24 – 33 was discovered in 2012, allowing for an additional high-voltage output from mechanical vibrations. With the aid of triboelectric, Wang et al reported respiration health based on AI-assisted diagnosis by multi-self-calibrated parameters from TENG with accuracy >95.21% 33 .…”
