Globalizer

   Do you find anything unusual in the picture? don't be puzzled by the colorful light, and make a comparison with our real life! …………..the truth is you can't discover any wire in the room! Researchers from Tokyo university are drawing this for us.

   Their idea is using plastic power transmission thin film to replace wire and plug. the film is a 4-layers film stack. from top to bottom, layers include power supply coil film, MEMS switch film, position sensing coil film and organic FET film. once the idea and prototype are proved, power transmission film can be inserted into wall, floor, desk, etc. thus, people can wirelessly get the electric power and our room will look like so neat than ever before. 

   If you can read chinese, this article is best for you to understand more. if you only know english, you can find a simpler introduction here. actually, Tokyo university is not the first idea-creator. several weeks ago, I read similar thinking from MIT TR although MIT's researchers didn't dig deeper than their Japanese peers.

   Myself is very interested in this technology. however, I have to ask researchers 2 questions:

   1) is it safe enough? like electromagnetic hazard, power leakage threat, etc.

  2) how to handle the heat? I think heat will be produced unavoidably when recharging or using electronics on the power transmission film.
