MIT creates an innovative smart diaper
The researchers of the American institute developed a sensor capable of detecting humidity, in order to notify the care responsibles
A group of 24 researchers at the Massachusetts Institute of Technology (MIT) in the United States developed a smart diaper with a moisture sensor that can notify caregivers when it is wet.
The sensor consists of a passive radiofrequency identification (RFID) tag that is located under the super absorbent polymer layer of the diapers.
The researchers, who published the information this week in the IEEE Sensors magazine, explain that when the layer gets wet it can activate the RFID tag to send a signal to an RFID reader that is up to a meter away.
In turn, the RFID reader may send a notification to a mobile phone or a computer, as detailed by MIT in a statement on its website.
The researchers also emphasize that RFID tags are more affordable than the technology used by other alternative smart diapers, since the manufacture of these sensors could cost around two cents.
