Research on Thermal Tactile Perception of Human Fingertips Using Temperature Control Device

摘要：

　　The thermal tactile perception principle of human finger was analyzed.Based on STM32 processor,the high-speed,high-precision,adjustable temperature control device was designed.Using the temperature control device,thermal tactile perception characteristics in human fingertips were studied,including maximum temperature,minimum temperature,and comfortable relationship in fingertips,temperature resolution ability,temperature remembrance ability,waveform recognition ability of temperature variation.Experimental results are as follows.The temperature resolution ability is higher near the body temperature in human fingertips,and the temperature resolution ability reduces when the temperature is too high or too low.The perception accuracy of temperature memory can improve effectively after training,and the perception accuracy of continuous touch is higher than discontinuous touch.The recognition rate of square wave is higher than triangle wave in temperature waveform recognition.
