This Mobile Phone Can Make Calls Even Without A Battery

Recently, a group of Washington University researchers in Seattle (United States) have built a mobile phone, for which there is no need for a phone to call, because it has the ability to get energy from the air.

A group of researchers at the University of Washington in Seattle (United States) have built a mobile phone that does not require batteries to make calls. Because there is the ability to get energy from the air.

The new prototype is the result of one year of work by this team. Its purpose was to be able to call a mobile without batteries, in the end, for which they had to face two major challenges: obtaining the required energy from the environment and reducing the power consumption of a call, which is usually 800 mg

First of all, researchers focused on resolving the issue of communication. For this, the prototype is based on a technique called backscatter, a physical phenomenon that reflects the waves, particles or signs from which they come.

A member of the Washington University researchers group in Seattle (United States), Joshua Smith, comes from working on a startup, a system called "passive WiFi", which is a digital backscaster for ultra low power WiFi The technology is the equipment However, this system requires a lot of energy for the project.

To solve the problem, secondly, they sought a method to reduce the power consumption of phone calls. The director of this research, Wamsi Tala, said, "Conversion of analog human voice consumes a lot of energy in digital signals" "It is more efficient to use analog technology." Thus, although the prototype uses digital signals to dial the number, but the backscitter process of voice calls is analog.

For example, the use of some remote components to save mobile energy without battery, for example, there is a base station with the circuit for the conversion and connection of the digital network, which is currently Skype prototype only active with fixed frequencies And can not be separated from the base of more than 15 meters.

It is necessary to enable domestic WiFi routers or traditional telephony towers for business development without phone. However, there is still a long way to go. The first step is to improve the quality of the call and create a new prototype with an efficient electronic ink screen for text message.
