Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Bioinspired Design of Extraordinary Wear‐Resistant Graphene/CoCrNi Multi‐Principal Element Alloy Composites

open access: yescMat, Volume 3, Issue 1, March 2026.
ABSTRACT The pursuit of simultaneously high wear resistance and excellent lubrication in multi‐principal element alloy (MPEA) composites is often hindered by a fundamental trade‐off, which is exacerbated by the agglomeration of high‐content graphene reinforcements.
