Researchers at the University of Colorado Boulder have invented a multifunctional wearable electronic system that combines advances in materials, chemistry and mechanics to enable superior stretchability, self-healability, recyclability and reconfigurability. This electronic system heterogeneously integrates rigid, soft and liquid materials through a low-cost fabrication method. Such multifunctional system can provide physical motion tracking, body temperature monitoring, and sensing of acoustic and electrocardiograph signals.
