A High Seebeck Coeffiecient Thermoelectric Generator Based on a Self-Healing Ionogel

In this work, we report a thermoelectric energy harvester based on an ion-conductive ionogel withthree distinctive features as compared with the state-of-art systems: (1) selfhealable in both thematerial and device operations under large deformations; (2) ultrahigh Seebeck coefficient withthe measured value of 7068 μV/K for the material, and 298 μV/K for a prototype energy harvesterin operations; and (3) stable performances under large bending states with little changes. As such,this energy harvester could find potential applications by further packaging and design inwearable devices to convert the temperature differences between human body/skin andenvironment to electricity.
