It could make everything you own “smart.”

IoT Time

Signs point to us eventually living in a world in which nearly everything around us is “smart.” Our clothes will send messages to our smartphones letting us know when they need washed, and our milk will order its own replacement as its expiration date nears.

But before the Internet of Things can fully take hold, we need to figure out a cheap and versatile way to give all these objects the ability to communicate — and the world’s first battery-free Bluetooth chip just might do the trick.

Stealing Power

On Monday, Israel-based semiconductor company Wiliot demonstrated a first-of-its-kind Bluetooth chip at the National Retail Federation’s (NRF) annual retail expo.

The chip is paper-thin and about the size of a postage stamp. It can sense weight and temperature and is able to send encrypted information via Bluetooth a distance of about 3 meters. Rather than using some sort of battery to power this operation, the chip pulls energy from ambient Wi-Fi, Bluetooth, and cellular signals.

Following the NRF demonstration, Wiliot announced that it had raised an additional $30 million in funding, with tech powerhouses Amazon and Samsung both investing.

Sticker Shock

Wiliot is confident that its battery-free Bluetooth chips will help us realize the promise of a fully connected world.

“Re-cycling the radiation around us to power sticker-size sensors can enable new ways for consumers to interact with products that were previously not feasible,” Wiliot CEO and co-founder Tal Tamir said in a press release. “Products can share when they are picked up, their temperature, or when they need to be replenished.”

“Without batteries or other high-cost components,” he continued, “tags have unlimited power and lifespan, so [they] can be embedded inside of products that were previously unconnected to the Internet of Things.”
