➀ Researchers developed a stretchable thermoelectric elastomer that converts body heat into electricity, enabling self-powered wearables and medical implants;
➀ The rubber-like material maintains high flexibility (up to 850% strain) and electrical conductivity through a polymer-N-DMBI composite design;
➂ Potential applications include health monitors, smart textiles, and implantable devices that harvest continuous energy from skin temperature gradients.
