This Paper is a study on the development of an active palpation sensor that is wearable on a doctor's finger and can compensate the force to press against prostate for detecting prostate cancer and hypertrophy. The receptor of the sensor is a polyvinylidene fluoride (PVDF) film. A strain gauge that is used to detect the force is attached to a metal base. This sensor section is set in a finger stall in order to take stable contact between a user's finger and the sensor. The sensor is pressed against the prostate gland and driven sinusoidally with a constant amplitude vibration. For convenience, the structure is made up of two parts: sensor and vibro-machine. The sensor is worn on a doctor's finger tip and a vibro-machine is fixed at his finger root. With this structure, the doctor can move his finger freely. The results showed that the output of the sensor varies with the stiffness of prostate glands and the sensor is effective in diagnosing the condition of prostate glands.
