Scientists have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). According to the researchers from North Carolina State University, the sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving. Long-term ...
