Wearable sensor clears path to long-term EKG, EMG monitoring
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 ...
Glass for battery electrodes
Today's lithium-ion batteries are good, but not good enough if our future energy system is to rely on electrical power. Chemists and materials scientists at ETH Zurich have developed a type of glass that ...

Extra-short nanowires best for brain
If in the future electrodes are inserted into the human brain - either for research purposes or to treat diseases - it may be appropriate to give them a 'coat' of nanowires that could make them less irritating for the brain ...
