Researchers Find Nanowires Have Unusually Pronounced ‘Anelastic’ Properties

Researchers have found that nanoscale wires (nanowires) made of common semiconductor materials have a pronounced anelasticity – meaning that the wires, when bent, return slowly to their original shape rather than snapping back quickly.

Wearable Sensor Smooths Path to Long-Term EKG, EMG Monitoring

Researchers have developed a wearable sensor that uses silver nanowires to monitor electrophysiological signals. The sensor is as accurate as the “wet electrode” sensors used in hospitals for EKGs and EMGs, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
