Body Heat??

Is it possible, a smart watch that is powered by body heat?

Wearable healthcare and fitness monitors are expected to be important IoT applications.

But manufacturers are just scratching the surface of what wearables can do, and often compromise one consumer demand for another.

So one interesting announcement at CES 2017 exhibition next month will come from Ambiq Micro, which specialises in low-power ARM processors.

Ambiq Micro says it has a design-in for a smartwatch that can run on body heat.

According to the company, this is possible because of is very low power processor technology, which operates at sub-threshold voltages.

Its latest ARM Cortex-M based processor is being presented as an IoT device with a power consumption of under 10µA/MHz.
