Stanford and University of California, Berkeley engineers have shrunk all the electronics found in a typical Bluetooth device into an ant-sized silicon chip that may solve the missing link between connecting smart devices and the Internet.
The radio chip is powered by electromagnetic waves that carry signals to its receiving antenna and no additional power source is needed. If a battery were needed, the radio could run on an AAA battery for more than a century. Prototypes of the devices were tested to receive signals, harvest energy, and send commands and instructions. The radio chips are very inexpensive to produce making them ideal for connecting smart electronics to the Internet for advancing the “Internet of Things.”
