Such tremulous movements are commonly observed in wrist flexion-extension (FE). To suppress this tremor we present a wearable robot (WR) with a customized mechanical metamaterial (MM) as the physical human-robot interface (pHRI). The MM is optimized to conform to the user\u2019s wrist posture and follow the hand\u2019s Cartesian trajectory. This is done to minimize the shear between the pHRI and the user\u2019s skin and consequently improve wearability. This WR is then used to effect a viscous tremor suppression using the velocity of the user\u2019s wrist FE. We present a model for the interaction between the WR and the user with which we develop the viscous damping approach for tremor. This is then evaluated in simulation and using a dedicated test bed. This tremor suppression approach demonstrates an attenuation of 20\u201330\u00a0dB at various tremulous frequencies resulting in significantly lower tremor amplitudes due to the viscous damping.<\/jats:p>","DOI":"10.1017\/wtc.2024.15","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T04:25:47Z","timestamp":1733804747000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Viscous
