Dual crosslinked ionogels with high stretchability and self-healing ability for wearable motion and thermal sensors

An effective strategy was proposed to fabricate high-performance ionogels in which the polymer chains were dual crosslinked by hydrogen bonding and vinyl hybrid silica nanoparticles. The synthesized dual crosslinked ionogels exhibit excellent stretchability and self-healing ability. The skin-type wearable sensor based on the dual crosslinked ionogel is assembled, which can be attached to a part of the human body to monitor various motions. Besides that, the wearable sensor can also serve as a fever monitor to indicate the human temperature instantaneously offering promising and strong practicability in wearable electronic devices.
