Smartwatch that converts body heat into a power supply

Limited battery power in smartwatches reduces their efficacy when sometimes our requirement for them to be functioning is crucial.

Heat-sync utilises thermoelectric technology to create an autonomous stable power supply by converting body heat into electrical energy. The device works by transforming the temperature differences between two axes: the heat from the wrist and the stainless-steel case as a heat sink. The greater the differences, the more power can be generated, reducing energy burden, whilst providing a quality display.
