Researchers of Tokyo University, MIT and Microsoft have realized the dream of electronics engineer !
They published today , at UbiComp conference, a new paper showing the possibility of printing electrical circuits using a home inkjet printer with special ink developed by Mitshubishi.
Many applications such as RFID, sensors, PCB, etc. can be applied from this technology.
