Self-powered diaper monitor system detects pee-pee, maybe one day poo-poo

Self-powered diaper monitor system detects pee-pee, maybe one day poo-pooIt’s not that hard for a parent to figure out if their toddler has peed their diaper, but when it comes to old folks, maybe it could be a big help. A research laboratory at Japan’s Ritsumeikan University has developed a monitoring system for wet diapers. It consists of a self-powered sensor/transmitter and a receiver and is designed to assist the staff in hospitals and nursing homes with diaper checks. The sensor kit needs to be placed inside the diaper and then it sends signals to the receiver.

The sensor and the wireless transmitter are powered by a built-in battery that generates electricity using a chemical reaction in the presence of urine. That’s when you know. You have pee-pee.
