Palpation is a simple diagnosis method that doctors examine body and organs of patients by feeling with their hand. However, palpation is not objective because the palpation sensitivity depends on skill and experiences of doctors. Therefore, an objective method for measuring tactile information is required. In previous studies, a tactile sensor which can measure the mobility of tumors is proposed. Mobility is important information to determine the malignancy of tumors. In this study, to investigate mobility of abnormalities, we performed sensory evaluation and the tactile sensor evaluation using palpation models with abnormality. From the comparison of the results, it was found that there is a strong correlation between mobility evaluated by the tactile sensor and mobility by humans Therefore, it is confirmed that the sensor is available to evaluate the mobility that humans feel.
