Charging mobile phone by Air

After telling about the history of Nokia, this time we talk about the latest technology to be issued by Nokia. Recently, Nokia states that in the next few years, they will be able to charge mobile phones using radio waves are all around us. Technology that makes me curious as well good this could lead to a massive reduction in energy demand if all mobile phones in the world capable of doing a charge back from the air.
Researchers at the Nokia Research Centre, Cambridge (UK) is working hard to create a technology that can collect small amounts of energy from radio waves and TV. This mobile phone will take a low-frequency radio waves at 500 megahertz to 10 gigahertz, which is derived from including broadcast TV, microwave ovens, mobile phones, wireless LAN, Bluetooth, GPS, and radio-two-way radio. According to his theory, the two circuits will be able to receive free energy and convert it into electric current to charge the battery on a cell phone.

Hopefully, this will be enough to create a charged cell phone in standby mode, although at first may not be able to deduct the time the phone is used, or to charge the batteries fully. Markku Rouvala, one of the researchers who create these devices, said “The trick is to ensure that these circuits using power is smaller than the energy received.” So far the device they were able to muster the energy for 5 milliwatt, and their short-term goal is to be able to muster the energy to 20 milliwatt, which is sufficient to charge the phone in standby mode. In the end, with an energy of 50 miliwatt is ideal and is able to slowly to charge batteries.
This technology can also be applied to the gadget-to charge other gadgets like MP3 palyer, portable game player, or other handheld devices. Nokia also not rely entirely on this technology. They also are using photovoltaic cells (solar cells) in research on energy sources and mobile phones are expected in the next three years we can already see the results.

M2E never built a power electronics technology Utilizing the motion (kinetic) for military purposes. Today they will use it for commercial applications are for a revolutionary mobile phone batteries. This technology is claimed to be producing 300 to 700 percent greater power from the kinetic energy technologies at the moment, and will eventually replace conventional mobile phone batteries.
M2E technology is based on Faraday’s principle, ie the energy produced from the movement of a magnet through a coil. Their design consists of one generator coil / magnet tiny batteries combined with traditional storage that will accommodate even the low-frequency kinetic energy, so almost all of everyday human movement would be converted into enough electricity to mentenagai electronic devices such as mobile phones, Smartphones , or MP3 player.

M2E is also currently applying this technology in other fields. Benefit from MEMS technology (MicroElectroMechanical Systems) is called will be very interesting and could be used widely. M2E also expect the kinetic-powered batteries will eventually be able to compete with conventional battery cells – D, AA, and even AAA.
It may take up to two years ahead we can expect our mobile phones will be able to deduct himself only by placing them in his pockets.
