PJT Pied - Instrumented Foot Model
Biomechanical model to study synthetic turf injuries
Overview
A biomechanical foot model with embedded strain gauges to study foot-shoe-surface interaction on synthetic turf and guide safer athletic footwear.
Problem / Context
Synthetic turf increases lower-limb injuries. The project aims to quantify stresses during abrupt movements and inform footwear and surface design.

Process
- - Context research and state-of-the-art review
- - Define functional needs and injury targets
- - Design lamella geometry for constant strain
- - CAD modeling in NX with cable routing
- - FEA with mesh refinement (CATIA V5/NX workflows)
- - Iterate geometry based on stress results
Key design decisions
- - Use strain gauges on a lamella to capture load paths
- - Model the lamella as a beam for predictable strain distribution
- - Refine mesh locally where stresses peak to improve accuracy
Engineering details
- - Load case: 850 N; material: ABS
- - Initial mesh 2 mm refined to 0.3 mm
- - Foot STL used as base geometry; cable channels integrated
Outcomes
- - Validated stress regions for sensor placement
- - CAD + simulation package ready for physical prototyping

What I would do next
- - Fabricate the instrumented foot and calibrate sensors
- - Run athlete trials on synthetic turf
- - Translate findings into footwear cushioning guidance
