Overview of Human Thermal Responses to Warm Surfaces of Electronic Devices

Literature was reviewed and summarized on a few topics including: existing standards about the limits of devices' surface temperature, recent studies on the devices that caused discomfort and skin damage, human thermal sensation thresholds, the factors that affect thermal sensation, and the subjective ratings in the studies of thermal sensation. At the end, recent research on human subjective and objective testing was also summarized. The purpose of the review is to give an overview of cutaneous human thermal sensation and comfort, and how they are affected by the surface temperature of electronic devices.
