Wearable, Washable Heart Sensor

Mar-13-17 A washable heart sensor that can be embroidered directly onto clothing could find its way into medical supplies as well as fitness gear.

The sensor is woven from a fiber optic thread, which was made by melt-spinning a polymer coating and a fiber optic polymer able to transmit light over great distances. That thread was then used then to create a sensor that can be embroidered into existing materials, and stand up to washing.

In tests, the sensor was as accurate as conventional fingertip sensors at measuring heart rate.
