A group of engineers from the University of Tokyo, led by Professor Takao Someyi, has developed a unique diaper sensor, which will be of great help in the care of young children and the elderly in the future.
The principle of its operation is quite simple - it works when wet. The corresponding signal is immediately transmitted wirelessly to a mobile device with a special application installed. All that remains is to change the diaper.
The sensor is made from organic materials by printing on an inkjet printer and will cost only a few cents. In the future, the developers want to go even further and create sensors that, in addition to humidity, will track the pulse, temperature, pressure and other parameters of human life.
