A Multimodal Haptic Interface for Simultaneous Softness and Thermal Modulation
A Multimodal Haptic Interface for Simultaneous Softness and Thermal Modulation
This research presents a tactile display technology capable of simultaneously modulating softness and temperature. The prototype utilizes particle jamming for stiffness control and thermal transfer via heated or cooled water for temperature modulation. Mechanical evaluations show a controllable stiffness increase of 300%, while thermal characterization confirms surface uniformity across a range from 10°C to 50°C. Closed-loop control maintains a setpoint error of 0.2°C. The work targets applications in perceptual research, medical simulation, and affective haptics.
The prototype demonstrates simultaneous control of stiffness and temperature with a reported closed-loop error of 0.2°C, though the abstract does not specify deployment readiness or safety certifications.

A prototype display, based on particle jamming and the thermal transfer of heated and cooled water, is evaluated in terms of its ability to change both stiffness and temperature. Mechanical evaluations demonstrate controllable stiffness increase of 300%, whilst thermal characterisation showed strong surface uniformity and a range of achievable temperatures from 10{\deg}C up

arXiv:2611.08398v1 Announce Type: new Abstract: Haptic interactions, such as touching an object in virtual reality, involve detecting a plethora of sensations through the skin. Whilst tactile displays exist to simulate and manipulate all of these cues individually, little progress has been made constructing devices that can control multiple cues simultaneously. This paper presents a tactile display technology that of
