Bio-inspired color-changing and self-healing hybrid hydrogels for wearable sensors and adaptive camouflage

Abstract

Hydrogel has been extensively investigated for its unique mechanical and ionic conductive properties. However, the applications of conventional hydrogels have been limited for their poor durability and low external perception....

Dual-Stimuli-Responsive and Anti-Freezing Conductive Ionic Hydrogels for Smart Wearable Devices and Optical Display Devices

“…PGG hydrogels have a very wide operating temperature range (−25–85 °C) (as shown in Table S1). The stable, freeze-resistant, highly ductile, and fast strain response of PGG hydrogel will provide more possibilities for wearable smart devices. − …”

Swelling-resistant microgel-reinforced hydrogel polymer electrolytes for flexible all-in-one supercapacitors with high performances

“…The samples were then removed and wiped with filter paper to remove the surface residue. The swelling ratio of the samples was determined by (h/h 0 ) 3 , where h and h 0 were the thickness of the swollen and initial samples, respectively.…”

“…The boom in wearable smart electronics has driven the demand for flexible energy storage devices. [1][2][3][4][5] Although batteries are widely used as power sources for electronic devices due to their excellent energy density, supercapacitors are emerging as promising energy storage devices for portable function-integrated electronics due to their advantages of high-power density, long cycle life, fast charge/discharge, good safety and miniaturization. [6][7][8][9] Especially, all-in-one supercapacitors, a class of integrated supercapacitors with low interfacial resistance and mechanical stability under complex deformation, have received extensive attention.…”

Conducting gelatin/PAM DN hydrogels with high mechanical properties prepared using the photoinduced one-pot method for strain sensors

“…In fact, it was sufficient for the GF to meet the requirements of the sensing application. 51,52 Fig. 8 Tensile stress-strain curves (a), the corresponding tensile modulus (b), compression stress-strain curves (c), and the corresponding compression modulus (d) of hydrogels with various contents of acrylamide.…”
