Amazon and Samsung are both investors, and a full release planned for 2020
A new paper-thin Bluetooth chip that’s able to operate entirely without a battery could be about to solve this problem. The postage stamp-sized chip from Wiliot is able to harvest energy from the ambient radio frequencies around us, such as Wi-Fi, Bluetooth, and cellular signals, and use them to power a Bluetooth-equipped ARM processor that can be connected to a variety of sensors.
Wiliot says that the size of the Bluetooth chip, combined with the lack of any battery, means it can be produced cheaply and mounted on almost anything. The company gives several potential use cases for the technology. For example, it could be embedded in consumer products to provide easy access to a digital manual when the original paper version is long lost, or it could be put on a clothing label and used to communicate the optimal settings to a washing machine.
However, the fact that it can also be combined with sensors raises more interesting possibilities. In addition to tracking items through a supply chain, a temperature sensor could also report when items get either too hot or too cold. Elsewhere, a pressure sensor could detect when a food container is empty and automatically order a replacement, thereby making so-called smart fridges truly smart.
