Researchers Are Developing A Mobile Phone That Does Not Require Running A Battery




A group of Washington University researchers has developed the first model for a battery-free mobile phone and have made the first mobile phone call without a battery at all. This model-built phone is built with ready-made components through a combination of wireless power and power Small solar.

The pursuit of better batteries may be the ultimate weapon of technology makers in the race for the phone, smart phone and other devices that multiply in our lives and require more energy to work, which the group tried to work on to reverse this equation.

The phone receives light and radio waves from the ocean, said Shyam Gulakota, a co-professor at Paul J. College. “We’ve built what we think is the first mobile phone that works almost without energy consumption,” said Allen Allen, a computer science and engineering professor at the University of Washington.

The initial model of the phone requires a power of 3.5 microns, a microcontroller part of one million watts, which may bring an innovative approach that eliminates the need for a battery within portable devices. The solar cell contained within the phone, approximately the size of a grain of rice, can transmit the signal to a base station It is about 50 feet away.

The phone, which does not have any components such as the display screen, RAM or internal storage space, can send and receive audio signals only and a pair of headphones can be used to make voice calls.

The researchers devised a method to use small vibrations from the telephone microphone and loudspeaker to encode incoming and outgoing signals, which does not allow the phone to send and receive audio at the same time, instead the caller should press a dedicated button to send or receive during the call, Wireless from a real cell phone.

The phone relies on a nearby base station that transmits its transmission to the cellular network, in such a case via the Skype messaging application, where the base station provides the bulk of the phone’s operating power, which the phone receives from radio signals.

The phone generates a signal of its own by means of back dispersion, ie, a 180 degree deviation of radiation or particles, a technique that is already common in determining radio frequencies and the technology that uses radio waves to identify people or objects that carry encoded chips such as radio frequency identification chips that symbolize existing radio signals With new information and reflect it back to the receiver.

One of the major innovations of the phone is the use of analog audio signals instead of digital audio signals, which researchers say provide a large amount of energy, and the phone has additional power to increase its range of LED, which generates a potential difference or changes its electrical resistance when exposed to light, which Represents small solar panels.

Researchers are imagining the future when similar wireless technology is widely integrated into cell towers or Wi-Fi wireless routers, making battery-free phone calls everywhere virtual. On June 30, they published a research paper detailing the phone.
