Fall detection and autonomy for the elderly is front-and-center at CES in Las Vegas this year. Cherish Health introduced the $300 Serenity appliance that uses radar to cover a whole house with fall detection powers. Zoe Care is taking a different approach, by using existing Wi-Fi signals (and the way our bodies change how Wi-Fi reception works) to detect humans and their activities.

Using Wi-Fi signals is a pretty cool, non-intrusive solution that addresses the key issues of privacy and ease of use that often plague conventional remote monitoring technologies. The device doubles as a smart plug, and uses a sensor to gather and analyze Wi-Fi signals. If a fall is detected, these signals are translated into alerts on a mobile application. Covering up to 800 sq. ft., just one device can secure multiple rooms or even an entire floor, making it an efficient, cost-effective solution.
