Flexible sensitive hydrogel sensor with self-powered capability

Libin Han et al.

Summary: Flexible sensitive hydrogels have gained significant research interest in the fabrication of human-machine interfacial devices. However, the challenge of achieving high strength, ultra-toughness, and good conductivity in hydrogels, as well as the dependence on an external power supply, remains a major obstacle. In this work, researchers synthesized supramolecular crosslinkers and inserted them into a polyvinyl alcohol hydrogel, resulting in conductive hydrogels with improved mechanical and electrical properties. The optimized hydrogel exhibited high toughness, elongation at break, tensile strength, and Young's modulus, and demonstrated resistance to the side effects of saline ions. The hydrogel also exhibited enhanced conductivity and sensitivity, making it a promising candidate for self-powered multi-functional sensors.

Intrinsically adhesive, highly sensitive and temperature tolerant flexible sensors based on double network organohydrogels

Hongwei Zhou et al.

Summary: Flexible sensors with integrated high performances are fabricated utilizing double network (DN) organohydrogels, exhibiting outstanding temperature tolerance, high stretchability, tensile strength, self-healing ability, and transparency. Resistive-type strain sensors of DN organohydrogels achieve high gauge factor, low response time, large sensing range, and reversible sensing ability, while sandwich-shaped capacitive-type pressure sensors exhibit high sensitivity. These sensors can be applied in monitoring various human motions and subtle physiological activities, and further promoted as wireless sensors.
