An experimental study on the relation between friction force and real contact area [PDF]
Scientific Reports, 2021 Classical laws of friction suggest that friction force is proportional to the normal load and independent of the nominal contact area. As a great improvement in this subject, it is now widely accepted that friction force is proportional to the real ...

The role of skin mechanics in contact force variation under different friction conditions [PDF]
Scientific ReportsWhen grasping objects, humans actively adjust grip force in response to surface slipperiness and motion. Previous studies have showed that corrective actions occur after tactile afferents signal surface friction or slip events.

Handling Characteristics of Mems-Tweezers with Contact Surface Fabricated by Deep-Rie
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Methods for enhancing the gripping ability of microtweezers are examined in terms of friction force. Two aspects are investigated experimentally. One is a method for increasing the coefficient of friction of the handling part of the microtweezers.
