Application principle of plantar pressure acquisition system
Sensor array detects pressure distribution
The core of the system is a high-density pressure sensor array (such as capacitive or resistive sensors), which is distributed in the pressure plate or insole. When the foot touches, the sensor generates an electrical signal through deformation or resistance change, and captures the pressure data of each area of the sole in real time.
Signal conversion and transmission
The sensor converts the pressure signal into an electrical signal and transmits it to the computer system through the data acquisition module. In dynamic measurement, the system can record the pressure changes at different stages of the gait cycle (such as touching the ground, rolling, and leaving the ground).
Data analysis and visualization
The software processes the electrical signal into visual results such as pressure distribution diagrams and center of gravity trajectories, and supports static, dynamic and balance analysis, such as arch shape, gait symmetry, pressure peak and other parameters.
Common use scenarios
I. Medical and health field
Foot disease screening and correction: Detect abnormal pressure distribution such as flat feet, high arches, and diabetic feet, and assist in customizing corrective insoles or orthotics.
Rehabilitation assessment: monitor the gait recovery of stroke and cerebral palsy patients, evaluate the prosthetic adaptation effect and postoperative rehabilitation progress.
Chronic disease management: prevent diabetic foot ulcers through dynamic pressure monitoring, and provide objective data to support intervention plans.
2. Sports science field
Sports performance optimization: analyze the pressure characteristics of the soles of athletes when running and jumping, optimize technical movements and design shock-absorbing sports shoes.
Injury prevention: identify abnormal loads on the knee or ankle joints caused by abnormal gait, and formulate targeted training plans.
3. Shoe design and manufacturing
Ergonomic design: optimize the sole structure based on the foot pressure data of different populations to improve comfort and functionality (such as shock-absorbing design of running shoes).
4. Scientific research and education
Biomechanical research: explore the impact of foot structure on whole body mechanics, and assist in gait pathology or sports biomechanics research.
Campus screening: used for foot health surveys of student groups and early detection of foot development abnormalities.
Technology Extension
The system can also be combined with vestibular function tests (such as open and closed eyes balance analysis) to evaluate neural control ability and be used for fall risk prediction in elderly care.
