Battery-free watches: New tech uses thin films to generate electricity from body heat – NotebookCheck.net News
ⓘ see SourcesThe new tech in action Researchers from Seoul National University have engineered a completely flat, wearable power source that forces heat to flow sideways to generate electricity, promising a battery-free future for smart clothing and health monitors. Thermoelectric generators produce power by capturing the temperature difference between a warm surface and a cooler environment. While these devices hold immense promise for continuously powering wearable electronics using human bo...
