Self-Powered Biosensors May Open Up New Paths to Medical Tracking, Treatments

Wearable and implantable devices are currently used for a variety of functions, including health tracking and monitoring.    However, supplying energy usually requires cumbersome batteries and downtime due to recharging.    Now, an international team of researchers suggests that advances in materials and electronic design may be able to convert biomechanical energy into electric energy, paving the way for devices that can be worn and implanted but do not require constant recharging, acco...
