This paper is a study on the optimum design of a palpation sensor for detecting prostate cancer and hypertrophy. The receptor of the sensor is a polyvinylidene fluoride (PVDF) film placed on the surface of a matrix rubber base. The sensor is pressed against the prostate gland and driven sinusoidally, with a constant amplitude. The voltage signal from the PVDF film is integrated over the sampling period and is used as the output of the sensor for evaluating the stiflhess of the pressed prostate gland. The output strength of the sensor is dependent on the relative stiffness of the sensor base rubber to the stiffness of the object prostate gland Thus, the stiffness of the base rubber is of great importance to make the sensor output maximum and achieve the best discrimination of the normality and abnormality of the organ. The FEM analysis is introduced for the optimal design of sensor.
