It is well known that not a day has typed on his remote control, see the knock on the table due to malfunction? You change the batteries, same result! This is often a problem of poor contact, usually located around the stack, because it is heavy elements that bully contacts to their surroundings. This situation is changing with the remote without batteries NEC.
How to produce energy without input from an energy reserve? The method is known. Some materials are capable, when deformed under the force of a wave, to generate electrons. Usually used to produce a shrill sound, it will be used here in reverse. By using materials with piezoelectric properties for the design of the buttons on their remote that NEC engineers have managed to do without batteries. The energy produced is very low, but with the current electronic technology, consuming less energy, the result is positive and can use this principle.

The proposed remote control without batteries started since 2006 is the result of collaboration between NEC and Soundpower company specializing in the exploitation of wave energy.The two partners hope to market the first remote controls based on this technology by 2011.
