MIT Wetness Sensor Changes Diapers, Perhaps Wearables Game?

  • Written by:

Detecting a certain degree of moisture, ‘smart labels’ comprising a hydrogel and radio frequency identifi­cation (RFID) tag were developed by MIT researchers and embedded into diapers to alert caretakers of wetness. This study, published in the IEEE Sensors Journal, explains the absorbent hydrogel slightly changes its electrical conductivity when wet, expanding and allowing a passive RFID tag placed under it […]
