Vibe is an intelligent wearable device that can help monitor and improve muscle mobility. The wearable, which can be strapped onto the limbs using Velcro, features an innovative fabric interface that displays the user's muscle activity in real-time. When the user is not exerting any muscle activity, the fabric displays in gray. When the user contracts their muscles, the fabric covering the active muscle parts turns green, providing instant feedback on the user's physical activity. Vibe app visualizes user's mobility data to facilitate better communication between patients and therapists.
