Converting Body Heat Into Electricity to Power Sensors

The number of wearable technologies that use sensors as medical tools to track a person’s well-being – is on the rise. All of them – need an electric charge or a battery source to operate, but a handful of researchers are trying to take batteries out of the equation.

Elizabeth Lee takes a look at the emerging new technology.
