Journal of Biomedical Engineering
|October 1, 1982
Summary
This study reports on a novel footswitch using conductive rubber modules for gait analysis. Higher module density reduces contact force, making it suitable for footwear applications.
Area of Science:
- Biomechanics
- Materials Science
- Wearable Technology
Background:
- Gait analysis requires accurate and non-intrusive measurement tools.
- Existing footswitch technologies may present limitations in comfort or sensitivity.
Purpose of the Study:
- To evaluate the performance of a novel footswitch design for gait analysis.
- To determine the effect of conductive rubber module density and plug position on footswitch performance.
Main Methods:
- A footswitch prototype was constructed using conductive rubber modules in foam, brass shims, and an inner sole design.
- Contact switching force was measured in relation to varying module densities and plug positions.
- The footswitch was tested for suitability in gait analysis applications.
Main Results:
- Contact switching force was found to decrease as the density of conductive rubber modules increased.
- The position of conductivity plugs within the footswitch did not significantly affect performance.
- A module density exceeding 4 per square inch resulted in threshold forces below 30 N.
Conclusions:
- The developed footswitch is suitable for gait analysis due to its acceptable threshold forces and ease of integration.
- No modification of conductive rubber is required, simplifying construction.
- The design offers a promising solution for non-invasive gait monitoring in footwear.
