Researchers at the University of Arizona published a study in Nature Communications about a wearable device to detect early signs of frailty in older adults. The device is a soft mesh sleeve that fits around the lower thigh.
The sleeve is about two-inch-wide, 3D-printed and lined with tiny sensors. It monitors leg acceleration, symmetry and step variability and runs an artificial intelligence analysis on the device itself.
By sending only analysis results, not raw recordings, the sleeve reduces the amount of data sent and removes the need for high-speed internet. Results go to a smart device by Bluetooth, and the sleeve has long-range wireless charging so users do not need to plug it in.
