New diapers can notify parents when a baby has wet them

    Can you tell if someone is wearing a diaper?

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

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

    The team has equipped the diaper with a sensor that reacts to increased humidity, and a passive radio frequency identification (RFID) tag located under a layer of absorbent 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 sensor is less than two cents, and its range can be increased due to the amount of copper in the device. This diaper is versatile and can be used not only for babies, but also for the elderly or bedridden patients..

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