Compared to relatively mature audio and video human-machine interfaces, providing accurate immersive touch sensation remains a challenge owing the substantial mechanical neurophysical complexity of touch. Touch sensations during relative lateral motion between skin-screen interface are largely dictated by interfacial friction, so controlling friction has potential for realistic mimicry surface texture, shape, material composition. In this work, we show large modulation finger locally...
Abstract With the ubiquity of touch screens and commercialization electroadhesion‐based surface haptic devices, modeling tools that capture multiphysical phenomena within finger–device interface their interaction are critical to design devices achieve higher performance reliability at lower cost. While electroadhesion has successfully demonstrated capability change tactile perception through friction modulation, mechanism in is still unclear, partly due complex interfacial physics including...
With the commercialization of haptic devices, understanding behavior under various environmental conditions is crucial for product optimization and cost reduction. Specifically, surface dependence friction force electroadhesion effect on relative humidity finger hydration level can directly impact their design performance. This article presents influence finger-surface Mechanisms including changes to Young's modulus skin, contact angle change capillary were analyzed separately with...
Human haptic perception relies on the ability of sensory receptors underneath skin corneocyte layer to sense external load, where adhesion and friction play an essential role in nanoscale solid–solid contact. Energy dissipation present at surface interface due change separation distance during sliding contact was uncovered, but energy human finger cell-nanoprobe under humidity temperature conditions has not been investigated yet. In this paper, corneocyte-nanoprobe variation both humidity,...
