Shoe fitting evaluation: Simulating the shear force generation between the sock and shoe materials! Machine learning uses SVM (Support Vector Machine).
I would like to introduce the "Estimation of Shear Force Using Piezo Wire Sensors" conducted at the Department of Mechanical Engineering, Tokyo Denki University. Using a force gauge, vertical loads were applied to stacked materials, and tensile tests were conducted using a motor under a total of 55 conditions, including 11 vertical load conditions and 5 motor voltage conditions. The estimation accuracy of the shear force was 92.5% for sensors processed into a circular shape and 93.1% for sensors woven into fabric. 【Key Points】 - Estimation of shear force from vibration measurements using piezo wire sensors - Real-time three-dimensional visualization of shear force and vertical load inside shoes *For more details, please download the PDF or feel free to contact us.
