New diapers can notify parents that the baby wet them

Researchers have developed a smart diaper with a built-in humidity sensor that can send notifications to a smartphone or computer when it gets wet.

While some children react violently towet diaper, others for a long time do not pay attention to it. However, prolonged use of a wet load can lead to painful rashes and inflammation. Now researchers from the Massachusetts Institute of Technology have proposed an innovative solution to this problem.

The team equipped the diaper with a sensor that reacts to increased humidity as well as the labelpassive radio frequency identification (RFID) located under a layer of absorbing polymer. When the diaper gets wet, the material between them swells and becomes a weak conductor, which is enough to send a radio signal to a reader within a radius of 1 meter, which in turn can send a notification to a smartphone or computer.

According to the developers, the cost of the sensorless than two cents, and the radius of its action can be increased due to the amount of copper in the device. Such a diaper is universal and can be used not only for infants, but also for the elderly or bedridden patients.

Recently, researchers also developed an application that detects signs of eye disease in a photo before doctors.
