Wiliot, an Israel-based semiconductor company, recently unveiled a sticker-sized battery-free Bluetooth sensor. According to Williot, their breakthrough Bluetooth technology harnesses ambient radio waves to power itself.

“We believe that disposable electronics based on battery-free, low-cost systems are the foundation for future IoT systems. We are on the edge of dramatically changing the way products are made, how they are distributed, where and when they are sold, and how they are used and recycled,” Tal Tamir, Wiliot co-founder and CEO, said.

“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. Products can share when they are picked up, their temperature, or when they need to be replenished. Without batteries or other high-cost components, tags have unlimited power and lifespan, so can be embedded inside of products that were previously unconnected to the Internet of Things.”

Wiliot Battery-Free Bluetooth Chip

Wiliot’s battery-free Bluetooth chip is roughly the size of a postage stamp. The device includes an ARM processor, temperature sensor, weight sensor, and cloud-based decryption and authentication.

The researchers glued the chip to an antenna printed on plastic or paper. Once attached, the miniature device can authenticate the distance of a product by transmitting an encrypted serial number. Then, it can finally communicate with the product through Bluetooth Low Energy.

“Wiliot’s strategy for battery-free Bluetooth transponders, which sense and communicate without needing specific action by consumers, is very relevant to Avery Dennison’s intelligent label strategy,” Francisco Melo, Vice President and General manager for Global RFID of Avery Dennison, said.

Wiliot’s Bluetooth technology is not only cost-efficient, but its real-life applications are virtually endless. From tracking consumer goods to upgrading data on tags and packages, to enhancing the use of Internet of Things and communicating with smart home devices, it appears that there’s nothing the small device can’t do.

Do you think this chip will be fully commercially scalable?
