Researchers from North Carolina State University have
developed a new, wearable sensor that uses silver nanowires to monitor
electrophysiological signals, such as electrocardiography (EKG) or
electromyography (EMG). The new 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 monitoring of electrophysiological signals can be
used to track patient health or assist in medical research, and may also be
used in the development of new powered prosthetics that respond to a patient’s
muscular signals
