Slinky-Like Sensor Patch Adapts to the Body for Joint Monitoring

A new plastic sensor patch developed at the University of Michigan  uses electronic sensors to measure the full functional range of motion of complex joints like the shoulder, and is inspired by Kirigami, the Japanese art of creating 3D structures from cut paper. The cut patterns in the kirigami sensor open so that it follows the contour of the wearer's body naturally. This enables the sensor to be manufactured flat, which is key to making the device affordable. The sensor patch could improve physical therapy for joint injury cover and help with athletic training.

    00:00:01 (upbeat background music) SHTEIN >> In my job, which is for the most part of a desk job, I would get certain kinds of injuries, you know, overuse injuries from using the mouse too much. Or in sports, for cycling, for example, I crashed a couple of times. Broke my collarbone. Really painful recovery process. NARRATOR >> With their background in athletics, professor Shtein and PhD student Erin Evke decided to come up with a better solution to measuring a body part's range of motion. EVKE >> Currently there does not exist a good way to track the complex motions of your shoulder. And by applying kirigami design techniques, we're able to conform to all

    00:00:37 different parts of the body, including that of the shoulder. And then by placing sensors at specific locations on the substrate, you're able to capture this motion. This can be incredibly useful for physical therapy, sports training, or even for animation films or video games.
