Researchers develop novel liquid metal circuits for flexible, self-healing wearables

Imagine a stretchable and durable sensor patch for monitoring the rehabilitation of patients with elbow or knee injuries, or an unbreakable and reliable wearable device that measures a runner's cardiac activities during training to prevent life-threatening injuries. Innovations in wearable technology are often limited by the electronic circuits--which are usually made of conductive metals that are either stiff or prone to damage--that power these smart devices.
