Humanoid Identification of Fabric Material Properties by Vibration Spectrum Analysis

Sensors, 2018
In daily contexts, fabrics embodied in garments are in contact with human body all the time. Since fabric material properties—such as softness or fineness—can be easily sensed by human fingertips, fabric materials can be roughly identified by

Interface roughness effect on friction map under fretting contact conditions [PDF]

, 2010
In many industrial applications where fretting damage is observed in the contact (e.g. rotor/blade, electrical contacts, assembly joint, axe/wheel, clutch) the external loadings or geometry design cannot be changed. Therefore, the surface preparation and
