HIGHLIGHTS

  • The scientists at South Korea’s Electronic and Telecommunications Research Institute have invented a device that coverts human body heat into electricity.
  • The 11 cm long and 5 cm wide device can amplify the generated electricity to power wearable devices.
  • The device works upon the technology known as “biomimetic heat sink”, where a temperature difference ocuurs between the skin and the patch like structure attached upon the thermoelectric device.

The scientists at South Korea’s Electronic and Telecommunications Research Institute have invented a device that coverts human body heat into electricity. The 11 cm long and 5 cm wide device can amplify the generated electricity to power wearable devices. The device works upon the technology known as “biomimetic heat sink”, where a temperature difference ocuurs between the skin and the patch like structure attached upon the thermoelectric device, imitating the sweat glands structure. With an efficiency of above 80 percent even at low voltages, when six devices are modularized in a bundle, they can generate up to a commercialization level of 2~3 milliwatts (mW). The research team succeeded in generating a 35 microwatts per square centimetres (uW/cm 2 ) that was enough for lighting the letters “ETRI” on the LED display board by boosting the voltage generated from the six devices attached to the wrist of an adult without any batteries.
