A Voltage Meter and Smart Fabric Swatch

Caption

Materials chemists led by Trisha Andrew at UMass Amherst have developed a fabric that can harvest body heat to power small wearable microelectronics such as activity trackers. They produced and evaluated stretchy knitted bands of thermoelectric fabric that can generate thermo-voltages greater than 20 milliVolts when worn on the hand.
