A new A.I.-powered device developed by researchers at the University of Waterloo can reportedly detect unattended children — and animals — left alone in vehicles with 100% accuracy. The experimental technology uses a combination of radar and cutting-edge machine learning to make its predictions — which could potentially save lives.

“We developed a life-detecting sensor using contactless monitoring of the changes on the body surface,” Hajar Abedi, a PhD candidate who worked on the project, told Digital Trends. “[We look at] the characteristic movement of a living body, such as respiration, with the employment of electromagnetic waves. We used a low-cost, low-power millimeter-wave frequency-modulated continuous-wave radar sensor for this purpose. We [also] developed an algorithm to identify occupied seats, [tracking] the number of occupants and their positions.”
