Monitor your heart rate using just underwear with the new wearable electrodes developed by NTT Japan

Japan telecommunication giant, NTT has developed wearable textile
electrodes which can be worn on the
inside of a shirt, and can continuously
monitor the electrical activity of the
heart over an extended period of
time.
The wearable electrodes are
fabricated from a conductive fiber,
consisting of a silk or a synthetic fibre
core coated with a conductive
polymer called PEDOT-PSS.

This conductive polymer has excellent
biocompatibility, and can deliver ECG
measurements with a stability
equivalent to that of conventional
medical electrodes, without the need
for attaching the electrodes to the skin
with an electrolyte paste or gel.
As the textile electrodes are soft to the
touch, flexible and breathable, long
term monitoring which places no
burden on the wearer is now
possible. Studies conducted by NTT
showed no signs of skin irritation or
contact dermatitis after long-term use.

NTT now plans to conduct further
experimentation, this time with 100
wearers, to further investigate their
safety and effectiveness.
In the future, these wearable
electrodes could be used to aid home
or remote medical care, reducing the
risk of heart attack through early
detection and treatment of heart
irregularities, or in fields such as
sports, general fitness and scientific
research.
