Battery-free IoT: this bluetooth-based tag harvests energy from radio waves

The internet of things sounds great, but has huge issues. Ubiquity is one. Battery power is another. Cost of sensors -- and sensing tech to sense the sensors -- is another.

But perhaps ... we're about to solve all the problems.

Wiliot makes a super-smart ARM-based chip with onboard sensors that harvests energy from environmental radio waves to enable battery-free IoT. In this episode of TechFirst with John Koetsier, I interview Stephen Statler, a senior VP at Wiliot.

The chip uses a custom-built operating system operating on nanowatt power and communicates to the cloud via standard Bluetooth. Cost looks to be an order of magnitude cheaper than RFiD.

We chat about what it can sense, how it works, what the use cases are, and much more.
