Nec invents the remote control without pile
If the piles are engineering problems and economic for user, they represent also an ecological catastrophe. According to Ademe, in 2005,28.592 tons of piles were marketing, that is to say approximately a billion units! On this mass of extremely polluting worn piles, only 9.049 tons were collected the same year, that is to say a rate of recycling close to the 32%. There exists however other solutions to avoid this pollution, for example by reducing the request. is precisely what research of engineers de Nec could allow, who developed a remote control which does not require any external power.
(To click to increase.) Worn piles, of waste embarassants. (DC) Jenny P. Since energy
is needed well, the engineers drew it from the ambient fish pond. For several years, laboratories have been devoted to the recovery of this ambient energy, heat and movements of the body or, quite simply, the noise. Qu they are sound or mechanical, the waves flood our daily newspaper indeed. The method is known. Certain materials are able, lorsqu they become deformed under the force a wave, to generate electrons. This phenomenon bears the name of piezoelectricity. is by using materials with the piezoelectric properties for the design of the buttons of their remote control which engineers de Nec managed to do without piles.
On the rails since 2006, this project of remote control without pile is the fruit of the collaboration of Nec and the Soundpower company, specialized in exploitation energy of the waves. The two partners hope to market the first remote controls based on this technology here 2011.
