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.
