Monitor Signals and Deliver Stimulations
Asian Scientist is reporting on the development by scientists in South Korea. They have developed an elastic mesh that can be used to monitor electrophysiological signals as well as deliver thermal and electrical stimulations. Wearable electronics have the potential to be useful diagnostics, such as in the monitoring of physical activity and cardiac function.
Stretchable and Conductive Patch
The researchers led by Dr. Choi Suji at IBS have invented a wearable device that can be used to record the electrical activity of the heart and muscles, that is, to produce an electrocardiogram (ECG) and electromyogram (EMG). The stretchable and conductive patch was created using gold-coated silver nanowires mixed with a type of rubber, called polystyrene-butadiene-styrene (SBS). The elasticity and stretchability of the device allowed it to follow the contours of flexible joints, such as the wrist.
