Palpation is important method for diagnosis. However, it is a subjective method, because diagnosis by palpation depends on skill and experience of doctors. Therefore, an objective palpation method is required. Tanaka et al have developed an active palpation sensor wearable on a finger for detecting prostate cancer. The sensor discriminated the hardness of prostate glands on the clinical tests. However, the sensor blocks feeling of the finger because the sensor part covers a finger pad. Measurement by sensor and palpation by a doctor at a same time will make better diagnosis. In this study, a nail-mounted sensor for measuring hardness of biological tissue with palpation by doctors was developed. Fundamental characteristics of the sensor were examined by using silicone rubber sample with different stiffness. From the results, it is confirmed that the sensor is available of discriminating hardness.
