Abstract: Objective To determine the technical indicators of flexural strength and loose performance of folding tactile sticks. Methods The bending strength and loose performance of 5 folding tactile sticks were tested, the displacement of the marked point were collected and analyzed with the motion tracking system. Results and Conclusion For the bending strength test, the maximum displacement of the central shall be ≤ 25 mm. For the loose performance test, the loose displacement shall be ≤ 5 mm.

Key words: folding tactile sticks, quality, flexural strength, loose performance
