In this paper, experimental result of modeling the transmission efficiency of the Bowden Cable System, BCS, is presented. BCS is an interface for the body-powered upper limb prosthesis, which has the potential of precise position and force control of the terminal device. However, the locus and the component's mechanical characteristic of the cable effects the operability of the prosthesis, and therefore, a theoretical model should enable quantitative evaluation for more desirable solution. Experiments were conducted with the off-the-shelf components, Bowden cables, housings, and liner, under the condition of an actual transhumeral prosthesis setting. Experimental results showed that the use of Teflon liner has superior characteristic of reducing the friction in the BCS, whereas, the theoretical model of transmission efficiency presented in preceding projects requires further investigation to improve the accuracy.
