A new blood pressure sensor about the size of a wristwatch should help ease the discomfort of patients who require continual blood pressure monitoring.
The device will be worn comfortably on the wrist, where it will measure the patient's blood pressure with an array of sensors. The sensors will monitor the contact pressure, pulse and blood flow on the surface of the skin near the wrist.
To account for the variances of pressure that will occur naturally on the surface of the skin as the device is worn, a sensor made from piezo-resistive fibers could be created. This will allow it to detect changes in pressure, convert the change to an electrical signal and transmit the data to the measuring device, increasing its measuring accuracy by more than 70 percent.
