As PSFK points out, "Heart rate monitors aren’t the most comfortable piece of equipment to wear for extended periods of time," that is why the NTT Heart Rate Monitor Undershirt could be very revolutionary for these types of situations. It is an unobtrusive monitor that is worn under regular shirts. Devoid of wires and bulky machinery, it goes virtually undetected by the wearer and completely by casual observers.
The NTT Heart Rate Monitor Undershirt was created after experiments with coating silk and synthetic fiber surfaces with PEDOT-PSS conductive polymer. The result was a flexible electrode that could be adhered to fabric instead of people's skin, which would naturally cause irritation over time. It has many applications.
