Recently, attempts to connect the virtual reality world with the real world have been actively conducted. Haptic devices that make you feel like you are interacting with real objects are at the center of the metaverse technology because they can make virtual reality more realistic when you interact with objects in virtual space. In order to further enhance the sense of reality, it is important to transmit various sensations to the human skin. In particular, Warmth, which expresses feelings of comfort and love, is important for expressing emotions. Therefore, we developed a functional miniature heater array that changes color depending on temperature change. A miniature heater array was integrated through the patterning process of silver nanowires. A thermochromic liquid crystal film was stacked on the heater array to visually represent the change in temperature. Moreover, this device was integrated into a flexible substrate (polyimide) to attach to the human skin or gloves.
