Nokia has patented a new technology that will significantly extend the period of autonomic life for mobile devices, through conversion of kinetic energy into electrical. The mobile phone recharging element has the following scheme of operation: the board and accumulator are placed on a rigid frame attached to the body of a mobile phone through one or more piezoelectric elements. Thus any movements and vibrations of rolling compartment cause the generation of electric charges. These charges are redirected to the battery. This will hardly substitute a full charge of device from the network, but the time of work in autonomic mode will be extended uniquely. Unfortunately, at this moment it’s just a patent application and in fact it may take many years before we’ll see a workable phone Nokia, charged by using kinetic energy or piezoelectricity.
Previously, to extend the life of mobile phone’s battery solar panels were used. In particular, such mobile phones have been released by Samsung and LG. However, this method of charging the battery is not universal because of dependence from weather.
Another interesting model was proposed by Japanese company NEC. It presented a prototype of a remote control to your TV or any other device for home that works without batteries. The required energy is produced by a tiny generator that converts vibration from pressing the keys on the console into electrical energy.
