Bluetooth-enabled tags and trackers aren't entirely new, but they share one limitation. Except for the range limitations of Bluetooth itself. Because they need electronics to make them work, they need energy, usually the thinnest and smallest batteries. However, if semiconductor startup Wiliot succeeds in proving its new technology, they won't have to. Bluetooth trackers can be as small as a postage stamp or thin, and can almost get the power they need from the air.

Not aerodynamic, of course. Instead, Wiliot is taking advantage of the Holy Grail of wireless charging technology. That said, whatever RF is around, from Wi-Fi to cellular networks and even Bluetooth itself, can power the small ARM processor on the tag. From Wiliot chips to simple antennas, entire devices can be printed on disposable or reusable plastic or stamp-sized paper.

There is no doubt that although the appearance is simple, the function of this sensor tag is not limited. On the one hand, it can send an encrypted serial number, and the receiver can uniquely and securely identify itself. But what's even more impressive is that these tags can even transmit data such as weight and temperature.

The practical uses of this almost immortal Bluetooth sensor tag are almost limitless. These labels can not only retain the label of the product and avoid loss, but also can be used to convey other information that the text does not fit the product in a limited space. It can also be used on an increasing number of IoT devices to remind users how to use it.

Wiliot's battery-less Bluetooth sensor tags can definitely be game-changing, so there's no need to use short-range but limited technologies like NFC. Of course, if it becomes a commercial product. However, this is likely to happen as companies such as Amazon and Samsung invest in it.
