This paper is a study on the development of a compact palpation sensor with the aim of developing an automatic sensing system for detecting both prostatic cancer and hypertrophy in vivo and noninvasively. The sensor is an assembly of layered media with two PVDF (polyvinylidene fluoride) patches embedded in a soft matrix material. First, the output voltage signals from the sensor are measured when the sensor is attached onto a linear translation stage and pressed against soft sample materials with a constant stroke and constant oscillation frequency. Then, the data processing for extracting the information on their stiffness is detailed. Finally, the clinical data measured on the stiffness of hardened and normal prostate glands are presented, which reveals the potential of the present probe for a compact palpation sensor.
