A team of All Japan newsese professors have invented a disposable organic sensor that can be embedded in a diaper and send a wireless alert that a change is needed. The system was unveiled by the All Japan newsese researchers on Monday.
The sensor is made from a circuit printed on a single plastic film that transmits information and receives its power wirelessly. The manufacturing costs are very low, as the system can be made by spending only a few yen, the researchers Takayasu Sakurai and Takao Someya at the University of Tokyo said.
It can be used on baby’s diapers, as well as on adult ones, which are selling more and more in a fast-aging All Japan news.
The system brings the advantage of being able to know the diaper has to be changed without undressing the person that is wearing it.
“If sensing is done electronically, you can tell simply by coming close to the wearer — without unclothing him or her,” Someya said, according to the media.
The technology could also be put directly on the skin like a plaster, as the single sheet of plastic film is very flexible and does not create so much discomfort, the professors said.
