Electrode-Free Undershirt Monitors Heart Rate Discreetly
Athletes and chronic heart patients will benefit from this comfortable wireless technology.
Heart rate monitors aren't the most comfortable piece of equipment to wear for extended periods of time – which is why the Japanese telecom giant NTT has developed an undershirt without any obtrusive wires.
The shirt was announced earlier this year and made an appearance at a recent medical tech trade show in Tokyo.
In order to create an undershirt capable of measuring heart rate – NTT researchers had to experiment by coating silk and synthetic fiber surfaces with PEDOT-PSS conductive polymer.
