Mechanically Robust, Environmentally Resistant, and Piezoionic Polyzwitterionic Composite Eutectogels Based on Polysaccharide Complexation Strategy for Stable Voltage Output, Energy Storage, and Strain Sensing

). Thanks to its internal porous structure, the composite eutectogel can provide a stable piezoionic output and be used for pressure response and powering LED lights. In addition, supercapacitors and strain sensors assembled on the basis of composite eutectogels proved their potential for applications in areas such as energy storage and human motion monitoring. In conclusion, this study provides important guidance for the construction of biomass ionic network skeletons and the development of high-performance ion-conducting materials.
