Flexible wearable electronics

Engineers at North Carolina State University have designed a flexible thermoelectric energy harvester that has the potential to improve the effectiveness of existing power wearable electronic devices, using body heat as the only source of energy. In comparison to rigid devices, flexible devices have been known to be less efficient. Researchers wanted to utilise the best thermoelectric materials used in rigid devices in a flexible package, so that manufacturers wouldn’t need to develop new materials when creating flexible devices. Liquid metal in the flexible thermoelectric device allows for self-healing. Future research will focus on improving the efficiencies of these flexible devices, by using materials and techniques to further eliminate parasitic resistances.
