Abstract
AbstractIn recent years, the demand for quantifying the five senses has increased in the industrial and medical fields. In particular, the sense of touch is a complex sensation consisting of contact force, sliding force, and cold‐warm sensation. The cold‐warm sensation is perceived by the difference in heat transfer between the object and the skin, and the difference in the heat capacity of the object. In our previous research, we developed a MEMS tactile sensor that can measure contact force, sliding force, and cold‐warm sensation with a single sensor. However, the measurement of the cold‐warm sensation requires a long measurement time to stabilize the temperature and relatively high‐temperature conditions of 40°C or higher. In this study, we report on a method for measuring the cold‐warm sensation at a temperature similar to that of a human fingertip. © 2023 Institute of Electrical Engineers of Japan.
