Abstract: Provided is a pain detecting method including obtaining an electric signal from applied pressure and heat by using a sensor unit including a material exhibiting both the piezoelectric characteristic and the thermoelectric characteristic; separating a pressure signal generated by the pressure and a heat signal generated by the heat from the obtained electric signal; determining whether to generate pain data from each of the pressure signal and the heat signal; and outputting the pain data.
