Earlier this year NTT announced the creation of a new wireless undershirt designed to take biomedical recordings (such as your heart rate).
The technological innovation is in the form of coating fibers such as silk or synthetics with a conductive polymer.
Nippon Telegraph and Telephone Corporation (NTT, CEO: Hiroo Unoura, Tokyo) has developed a conductive fiber by coating the surface of silk or synthetic fiber with conductive polymer (PEDOT-PSS*1) and has used it to fabricate wearable electrodes with which to obtain biomedical recordings.
Conventional biomedical electrodes use an electrolyte paste or gel, which results in excessive wetting of the skin surface and occasionally causes skin irritation or contact dermatitis. The new bioelectrode made of conductive fiber without any electrolyte paste is flexible, biocompatible, and hydrophilic and so allows stable recording equivalent to that of a conventional electrode.
Experiments on 10 able-bodied human volunteers wearing undershirts equipped with the electrode revealed successful long-term recording of the heartbeat and electrocardiograms.
This result shows that the heartbeat and electrocardiograms can be monitored continuously simply by wearing the electrode shirts. We can expect the electrode to find various applications in sports, health enhancement, and the support of medical diagnosis, as well as scientific research.
Kinda reminds me a little bit of the undershirt that monitors people with Diabetes.
