Research on display that reproduces the thermal sensation perceived by human

In this paper, in order to propose an interface that reproduces a thermal sensation, the skin temperature change when a human touches an object was measured, and temperature reproduction was performed using a Peltier device. The response and followability of the Peltier device were evaluated in experiments using objects with different thermal properties. The results showed that the heat transfer was generally terminated when the object is touched for about 10 seconds, and after that the temperature change was small. Furthermore, using the manufactured thermal sensation presentation device, we attempted to generate the wet sensation of a plurality of dry fabrics. The subjects evaluated the wet sensation of the initial temperature controlled the fabrics (dry or having a moisture content of 20-30%). As a result we concluded that the wet sensation can be generated when the initial temperature of the dry fabrics is lower than the skin temperature.
