Thermogalvanic hydrogel with controllable ion confined transportation and its application for self-powered lactic acid sensor
摘要
Thermogalvanic hydrogels can convert low-grade thermal energy into electricity, but controlling ion transport remains challenging for stable and sensitive sensing. Here, a thermogalvanic hydrogel with controllable ion-confined transportation is developed through engineered micro/nano channels. The device enables efficient harvesting of body heat and serves as a self-powered lactic acid sensor without external power supply, demonstrating potential for wearable health monitoring applications.
