THERMAL SENSATION DISPLAY WITH CONTROLLABLE THERMAL CONDUCTIVITY

We demonstrate a thermal sensation display that can present various thermal sensation by varying the thermal conductivity of the display. Thermal sensation, i.e. cold/cool/warm/hot, is one of the major tactile sensations and needs to be further investigated to advanced VRiAR systems. Although many reports on the tactile displays present hoticold surfaces by changing the surface werature, the proposed display is the first one that can control thermal conductivity. The device contains liquid metal, whose contact to the top titanium plate determines the thermal conductivity of the device and thus, the thermal sensation presented to the users. This device can be a good platform for the study of thermal sensation.
