MIT scientists invent affordable smart diapers
15 February, 2020
Scientists from MIT attended up with a cheap and compact Radio Frequency Identification (RFID) sensor that can detect whether a baby has wetted its diapers.
These devices is even with the capacity of sending an aware of the caregivers when the toddler has finally done its thing, The Verge cited MIT News.
MIT researchers Pankhuri Sen, Sai Nithin R. Kantareddy, Rahul Bhattacharyya, Sanjay E. Sarma, and Joshua E. Siegel declare that the tiny sensor could be produced for under 2 cents, which makes it a feasible addition to mass-produced disposable diapers.
The RFID tag comes planted within the hydrogel -- an absorbent material -- of the diaper.
As the hydrogel becomes wet, it expands and becomes slightly conductive. This phenomenon then activates the tag which subsequently sends a sign to a near by RFID reader that's located within a metre from the infant.
The MIT article also revealed that all this happens without the utilization of any external power source, such as for example batteries.
When the disaster finally strikes, the RFID reader linked to the home Wi-Fi sends an alert message on the parent's smartphones.
Before this simple and ingenious invention, big names such as Pampers and Huggies launched their own smart diapers.
However, they were somewhat too high-tech for his or her own good and turned out to be too expensive, cumbersome and bulky.
