Wristband Revolutionizes Blood Pressure Measurement

Wristband Revolutionizes Blood Pressure Measurement


EMPA, the Swiss Federal Laboratories for Materials Science and Technology, developed a innovative wristband sensor to measure blood pressure. This medtech innovation came to life through industrial cooperation between EMPA laboratories and STBL Medical Research AG (STBL).

EMPA’s Laboratory for High Performance Ceramics produced a sensor made from piezo-resistive fibres in the wristband that measures the contact pressure of the device on the skin. This sensor allows the detection of small changes in signal strength, and by measuring them enables the measurements to be corrected accordingly. The new device has an enormous potential, as the consequences of high blood pressure are one of the most common causes of death worldwide. Despite this, according to the World Health Organization WHO, fewer than one in two of those affected measures their blood pressure regularly. The main reason for this is that regular measurements are costly. The “blood pressure watch” should change this and become accessible to a much wider range of people.
