With a vision to connect people with packaging and products using paper thin battery-free Bluetooth sensors, Israeli startup Wiliot has raised $30 million in series B funding with Amazon Web Services (AWS) Investment Arm, Samsung Venture Investment Corp., and Avery Dennison.

The new investors have joined Norwest Venture Partners, 83North, Grove Ventures, Qualcomm Ventures, and M Ventures to raise an additional $30 million of funding. This follows its demonstration of the first-ever sticker-sized Bluetooth sensor tag incorporating an ARM processor powered solely by scavenging energy from ambient radio frequencies.

A Wiliot chip glued to a simple antenna printed on plastic or paper can authenticate the proximity of a product by transmitting an encrypted serial number along with weight and temperature data from a device the size of a postage stamp. Eliminating most of the components associated with traditional Bluetooth, these tags lower sale and maintenance costs to previously unachievable levels. The tags use Wiliot’s breakthrough in nanowatt computing to communicate with any device enabled by Bluetooth Low Energy, such as smartphones, Wi-Fi access points and Internet of Things (IoT) devices that can connect to digital displays, Wi-Fi and LTE cellular networks.

“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,” said Tal Tamir, Wiliot CEO and co-founder.
