Skin sensors monitor brain, heart and muscle

They incorporate electrophysiological, temperature and strain sensors, which were used to monitor electrical activity from the brain, heart and skeletal muscles. The system can be attached to the skin for 24 hours and power can be supplied with solar cells or wireless coils. This research opens up a new way of monitoring heart and brain activity without the need for bulky equipment, the authors say.
