No sweat! Lightweight, wearable tech converts body heat to electricity

The video discusses a new design for wearable thermoelectric generators (TEGs) developed by researchers at North Carolina State University. These TEGs convert body heat into electricity, offering a lightweight and flexible alternative to previous designs. The TEG armband can generate up to 20 microwatts of power per square centimeter, while TEGs in t-shirts can generate up to 16 microwatts when running. The goal is to create battery-free wearable tech for long-term health monitoring. The video concludes with a humorous exchange about the Game of Life.
