According to the Japanese media, a research team consisting of the Japan Institute of Chemistry and Chemical Engineering and the University of Tokyo published a statement in the British science journal Nature & Energy (electronic version) on the 18th of this month that it has developed a scalable and washable Ultra-thin solar cells. It is reported that the user can be attached to the clothes, as a wearable machine power supply. Reported that the researcher Fukien Kenjiro and the University of Tokyo stained Professor Takahiro and others, will own the semiconductor nature of the organic compounds applied to the ultra-thin polymer film to produce solar cells. It is reported that the thickness of only 3 microns, even if bending can press normal operation. Fukuda said: "Putting it on shirts and other clothes may also serve as a power source for machines that measure blood pressure and body temperature all the time, medical devices that detect diseases early, and thin smartphones integrated with clothes."
