Wearable Electronics for Continuous Cardiac, Respiratory Monitoring

A small and inexpensive sensor, announced in Applied Physics Letters and based on an electrochemical system, could potentially be worn continuously by cardiac patients or others who require constant monitoring. A solution containing electrolyte substances is placed into a small circular cavity that is capped with a thin flexible diaphragm, allowing detection of subtle movements when placed on a patient’s chest. The authors suggest their sensor could be used for diagnosis of respiratory diseases.

Study Shows Hydroxychloroquine’s Harmful Effects on Heart Rhythm
