Abstract: Thermal grill illusion (TGI) is a phenomenon involving a painful or burning sensation that is perceived when warm and cold stimuli are simultaneously placed on the skin. We proposed that the TGI can be generated by directly activating transient receptor potential channels, which contribute to temperature perception, with chemical substances such as capsaicin and menthol. This method enables the energy-saving and compact presentation of pain sensations. We examined the reactions of the study subjects to each chemical and then applied two chemicals to the same or adjacent parts of the skin to verify the generation of the TGI(n = 10). The results suggest that the application of capsaicin and menthol next to each other generates the TGI.
