Carbon Black Based Resistive Strain Gauge Sensor for Penile Measurement

The accurate measurement of erection ability of men is important for prognosis of urinary surgery as well as for mental health. However, conventional penile size measurement methods are less accurate, and the intervention of doctor or nurse in the process can cause the patient to feel sexual humiliated. In this paper, in order to measure the erection correctly, the condom type sensor is fabricated with resistive strain gauge using carbon black. The resistive strain gauge is fabricated on the latex condom by spraying the carbon black diluted with the water. In the fabrication process, the pre-stretching technique is also applied to increase the flexibility of the sensor. The performance of the sensor is measured through the experiment with digital multi meter.
