Design of Variable-friction devices for shoe-floor contact

Design of Variable-friction devices for shoe-floor contact

In rehabilitation training, high-fidelity simulation environments are needed for reproducing the effects of slippery surfaces, in which potential balance failure conditions can be reproduced on demand. Motivated by these requirements, this article considers the design of variable-friction devices for use in the context of human walking on surfaces in which the coefficient of friction can be con...

Development of a Computational Model for Shoe-floor- Contaminant Friction

A Dynamic Coefficient of Friction Measurement Device for Shoe/Floor Interface Testing

A dynamic coefficient of friction (COF) measurement device is described for use in recording shoe/floor slip resistance. This device is computercontrolled and allows changes in the shoe/floor interface velocity and vertical force applied during a test. Different sole materials, floors, and contaminants such as water or oil are testable. Repeatability tests of the device were conducted of four v...

Temporal Changes in the Required Shoe-Floor Friction when Walking following an Induced Slip

Biomechanical aspects of slips and falls have been widely studied to facilitate fall prevention strategies. Prior studies have shown changes in gait after an induced slipping event. As such, most researchers only slip participants one time to avoid such changes that would otherwise reduce the external validity of experimental results. The ability to slip participants more than once, after allow...
