This 'smart bandage' monitors a range of health signals and connects wirelessly
FirstpostWhen worn on the forearm, it can record muscle activity and used to remotely control a robotic arm. Scientists have developed a stretchable 3D ‘smart bandage’ that can help wirelessly monitor signals, from respiration, to eye movement, to heart and brain activity, as well as a robotic arm. On the forehead, it records brain signals like a mini EEG sensor, and when placed on the side of the head, it records eyeball movements. We picked high quality, robust sub-components — the best strain sensor we could find on the market, the most sensitive accelerometer, the most reliable ECG sensor, high quality Bluetooth, etc — and developed a clever way to integrate all these into one stretchable device,” said Yang Li, graduate student at the University of California-San Diego. The islands are connected by stretchy ‘bridges’ made of thin, spring-shaped copper wires, allowing the circuits to stretch, bend and twist without compromising electronic function.
