  This paper introduces a motor-driven Peltier device designed to deliver
immediate thermal sensations within extended reality (XR) environments. The
system incorporates eight motor-driven Peltier elements, facilitating swift
transitions between warm and cool sensations by rotating preheated or cooled
elements to opposite sides. A multi-layer structure, comprising aluminum and
silicone layers, ensures user comfort and safety while maintaining optimal
temperatures for thermal stimuli. Time-temperature characteristic analysis
demonstrates the system's ability to provide warm and cool sensations
efficiently, with a dual-sided lifetime of up to 206 seconds at a 2V input. Our
system design is adaptable to various body parts and can be synchronized with
corresponding visual stimuli to enhance the immersive sensation of virtual
object interaction and information delivery.
