systems often suffer from poor durability due to the large dynamic load. This work presents a novel shoe-mounted sensor named Smart Lacelock, which takes the form of a common shoelace tensioning device (shoelace lock). With its unique form factor, the Smart Lacelock can be securely ...
We demonstrate potential of adaptive SCS to enhance foot stability and safety during dynamic movements, warranting further development in sports shoe design.
Such details provide a deeper understanding and appreciation for Adaptive Shoelace Systems Responding To Motion Dynamics.
- For the experiment on human being, Visual3D (V6.0, C-motion Inc., USA) was applied for data processing, and a Butter-worth fourth-order low-pass filter was used to filter the 3D kinematics, dynamics measured by the force table, and shoelace force data, with the cutoff frequencies set to 8 Hz, 50 Hz, and 20 Hz, respectively [13]. The shoelace tension data were processed and analyzed based on the synchronized kinematic data and the kinetics data captured by the 3D force platform as the baseline for intercepting the shoelace tension data for one complete gait cycle.
- High-speed video observation of in situ shoelace knot showed failure to be a sudden and catastrophic phenomenon. Observations point to a failure driven by the complex interplay between impact-induced deformation of the centre of the knot, dynamic swinging of the walking motion, and the inertial forces of the laces and free ends of the knot.
