要約(英語): The Blood flow monitoring with wearable devices has been used to detect blood flow disorders. Among various factors such as pulse wave, color, and temperature, this study focused on temperature measurement. In order to confirm the difference in the temperature response of the skin to heat input due to the difference in blood flow rate, we first simulated the temperature distribution of the skin using Pennes’ bioheat conduction equation to see the difference in the calculated temperature response. Next, we conducted animal experiments using a blood flow cutoff model to see the difference in the actual temperature response of the skin. Both the simulations and the animal experiments confirmed the difference in temperature response due to the difference in the amount of blood flow.
