Thermoplastic charge-transfer hydrogels for highly sensitive strain and temperature sensors

Abstract

Recently, flexible wearable electronics have drawn increasing interest in health monitoring, human motion detection, artificial skin, and so on, owing to their comfort of wear and the ability to transmit...

A Series of POM–Viologen Photo-/Electrochromic Hybrids and Hydrogels Acting as Multifunctional Sensors for Detecting UV, Hg2+, and Organic Amines

“…It has good flexibility, chemical stability, and environmental protection. Therefore, it is widely used in electronic wearable devices, sensors, biomedicines, and other fields . In addition, polyacrylamide (PAAm) hydrogels contain large amounts of lithium chloride, making them excellent for water retention in low humidity environments .…”

Thermochromic and conductive hydrogels with tunable temperature sensitivity for dual sensing of temperature and human motion

“…Skin-like sensors convert sensed external stimuli such as pressure and temperature into electrical signals, enabling visual monitoring of external environmental stimuli. 7–10 Traditional rigid sensors are less flexible and stretchable, making them limited in wearable electronics. Hydrogels are soft, stretchable, and biocompatible, making them promising flexible and stretchable sensors for smart wearable electronic devices.…”

Low-hysteresis and highly linear sensors based on environmentally stable, adhesive, and antibacterial hydrogels

“…Flexible strain sensors have rapidly developed in recent years, driven by their wide range of applications in electronic and biological elds. [1][2][3] One critical factor in evaluating the performance of exible strain sensors is their ability to accurately output signals. Both large hysteresis and nonlinearity can diminish signal accuracy.…”
