A team of engineers at Stanford University in collaboration with researchers from the University of California at Berkeley have developed a radio the size of an ant. This product has no battery and gathers the necessary energy from the electromagnetic waves that arrive at the receiving antenna.

“The next exponential growth in relation to the connection between the objects themselves, and we will be able to remotely control them via the Internet,” – said the associate professor of electrical Arbabian Amin (Amin Arbabian).

Amin began the project in 2011, when he finished graduate school and worked with the director of the research center Wireless UC Berkeley Niknedzhedom Ali (Ali Niknejad). His main assistant was his wife Maryam Tabesh (Maryam Tabesh), at that time a student in the laboratory Niknedzheda. Arbabian joined Stanford University in 2012.

Most of the necessary infrastructure, which may allow us to remotely control sensors and devices already exist: we have the Internet, to produce teams around the world, as well as computers and smartphones to run these commands. What is missing is an inexpensive wireless controller that is installed on any gadget.

According to the developers, if you connect the battery to the radio format AAA, then its energy would be enough to keep it in working order for more than one hundred years.

In order to build radiochip, it was necessary to alter’s radio and other settings, according to the website of Stanford University. The antenna should be small, as small as one-tenth of the antenna Wi-Fi , and work at an incredibly high rate of 24 billion cycles per second. Standard transistors could not easily handle signals that fluctuate so quickly.

But still managed to place Aminu all the necessary components on a single chip: the receiving antenna, which collects energy from the incoming electromagnetic wave transmitting antenna to broadcast a short distance, the central processor to interpret and execute instructions. No external components or batteries are not required.

Since radio is designed for the detection and transmission of commands and has a small value, it may be the missing link between the Internet and smart gadgets. Thus, it can be widely used in the field of “Internet of Things”.
