We developed a new blood-leakage sensor for hemodialysis therapy. In this sensor, medical gauze is arranged on medical adhesive tape, which contains detection electrodes formed by screen-offset printing. This sensor can be used similarly to an adhesive bandage. We proved that the sensor can distinguish between blood and phosphate-buffered saline (substitute for sweat) on the basis of the dielectric relaxation property of blood. The limit of detection of the sensor is as low as 6 μL, and hence, its performance is considerably better than that of other sensors reported previously.
