Concept of a phone that does not need a battery


At the University of Washington, a group of researchers developed a prototype phone, which in its construction does not contain a power source. The device is devoid of such a habitual feature of all modern mobile devices, as a battery, but also has not received any other energy storage device. Instead of a standard power source, it has a microwave resonator that works without batteries and can transfer vibrations created by the human voice to the nearby receiver. The digital station is connected to a mobile network, and the learned signal serves not only for data transmission, but also is converted into energy for powering other structural elements. Earlier, a similar scheme was used by Soviet intelligence to track the US embassy.
However, this solution has a lot of disadvantages associated with the extremely small amount of energy that can be generated by the microwave cavity. Developers had to abandon all the attributes inherent in not only a modern smartphone, but even an ordinary phone. Some components of the cellular, for example, the station responsible for contact with the network, had to be placed next to the phone to save energy. Since the phone receives signals from it, and then converts them into electricity, the station can not yet be removed far. In the future, developers plan to integrate the station into a Wi-Fi router installed on the telephone tower, and increase the distance.Future technology Concept of a phone that does not need a battery

Now the prototype has the usual buttons and a tiny screen – for the sake of saving energy it is necessary to save everything, and the quality of communication leaves much to be desired. In the immediate future, the developers plan to fix the situation, and then equip the handset with an E-ink display, which allows sending full text messages from the phone and monitoring various information. Then, if everything is be normal with the power consumption, the phone will be supplied with a camera.Future technology Concept of a phone that does not need a battery  Future technology Concept of a phone that does not need a battery Future technology Concept of a phone that does not need a battery
