Use power without wires or plugs

We often find 'eye-to-eye' because of the entanglement of the wire or socket in the house or around the desk ... The picture of the wire lurching, rolling around and then back to the past thanks to the plastic sheet wireless, newly invented by Japanese scientists. This resin allows flat surfaces such as ceilings - floors, walls, desks ... to power electronic devices, without the need for wires or plugs.

Wireless Transparency Plastic Sheet with a thickness of 1 mm and a weight of 50 grams can carry 40 watts of electricity to devices with special ' or near it. The amount of electricity generated by the plastic is enough to illuminate a light bulb or a small laptop.

The plastic sheet is composed of two sides, in which the bottom is a transistor layer containing pentacene - an organic molecule with conductive electrical conductivity. The upper side contains copper coil layers that can sense a compatible electronic device, while the MEMS (microprocessor-based microprocessor) switches act as power-off and the copper coils are conductive. . When the electronics are placed 2.5 cm from the plastic, the nearest MEMS switch is on and the power is supplied to the copper coil next to it, and it will charge the coil of the receiving device through inductor.

The inventors reported that the power transmission efficiency of the plastic sheet was 81.4 percent, compared with 93 percent of current electricity networks, with relatively low levels of electromagnetic radiation leakage. This invention, after being published, has attracted many companies interested in cooperating in commercial production.

Currently, the group is planning mass production of plastic pieces generators wirelessly to cost quite low, estimated at USD 100 / ^m2 to spread on desks, floors, ceilings and walls, opens generation new electronic devices. However, due to the need to be further improved technically, such as durability, power efficiency ... plastic sheet is expected to only appear on the market after 2012.
