Developed Bluetooth chip for IoT, powered by energy from ambient radio waves

Wiliot has developed a postage stamp-sized Bluetooth chip that does not require a battery to operate because it uses exclusively radio waves from Wi-Fi, Bluetooth, mobile phones and other devices to power its ARM processor..

The IoT network is growing rapidly and soon billions of devices will be connected to the Internet of Things. However, the need for a separate energy storage unit limits their minimum size and cost. The solution to this problem proposed by the team at California-based startup Wiliot, which created a Bluetooth chip attached to a paper sticker that can be easily connected to various sensors by linking them to the IoT.

The startup has already raised $ 30 million in investments from companies such as Amazon, Samsung and Qualcomm. Wiliot plans to release a trial batch of devices in 2019, and begin full-scale production in 2020. Engineers claim that the product is low cost, energy efficient and versatile as it can be attached to almost anything.

Representatives of the company cite several options for using their chips. For example, it can be embedded separately in consumer products to provide easy access to digital manuals if the paper version is lost, or applied to clothing labels and used to convey optimal settings to the washing machine..

However, the possibility of combining with sensors significantly expands scope application. In addition to tracking the movement of goods in the supply chain, the temperature sensor additionally may report overheating or hypothermia of the goods. Combine with a pressure sensor to detect when a food container is empty and automatically order replacements, making smart fridges even smarter.

We also reported earlier that a student at the University of Tokyo has developed a system for wireless charging of electronic devices in the form of a flexible sheet that can be formed into any shape or even cut with scissors.
