Synergistic Design of Composite Ionogels With Enhanced Thermoelectric Properties, Mechanical Stretchability, and Sustainable Recyclability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
While flexible TE devices hold promise for converting low‐grade waste heat (e.g., from human skin or electronics) into usable electricity, existing materials suffer from three major limitations: 1) poor mechanical stretchability (failing to match human skin's elongation, ~20–30%), limiting wearability; 2) tradeoffs between thermoelectric efficiency (e ...
