“Bend me, shape me” its not--more like flex me, but not too far. A research group from the University of Tokyo, lead by Professor Takeo Someya and Research Associate Tsuyoshi Sekitani of the Department of Electrical Engineering and Information Systems, Graduate School of Engineering, is showing off a flash memory module that can be flexed into an arc with a 6mm radius before suffering mechanical damage.
The module consists of 26 x 26 2T memory cells in an array structure placed on a polyethylene naphthalate (PEN) substrate. This “organic flash memory” is non-volatile (if a single day’s memory retention can be considered non-volatile), and has an erasing voltage of 6V and a reading voltage of 1V.
Researchers say the memory can be used for large-area sensors, electronic paper, or any device that requires its memory retention time extended. Also, because the sheet is pressure sensitive, it can easily be converted into an “intelligent pressure sensor”.
