Plantar Pressure Distribution System
The plantar pressure distribution system is a professional instrument that collects pressure signals from various parts of the sole through a high-density pressure sensor matrix.
The system adopts an array-type pressure sensor component to form a force-measuring plate, with a single-point pressure resolution reaching 0.1 N/cm, covering the biomechanical measurement requirements of 0–100 N/cm.
The standard size of the force-measuring plate is 2000 mm, adapting to stride characteristics of groups with different heights. The sensor units are designed in a miniaturized form of 5×7 mm to achieve high-density distribution, ensuring precise imaging of plantar pressure distribution.
The system realizes its functions through three modules:
- Data acquisition module: the pressure sensors on the force plate record in real time the pressure values of various sole regions.
- Signal processing module: analyzes data such as center of gravity, balance, and impulse through software.
- Data analysis module: by detecting dynamic and static load of the sole of the tested person, discovers gait abnormalities in hip, knee, ankle joints and diseases such as cerebral palsy and diabetes.
3D Foot Shape Scanning Technology
The 3D foot shape scanning system adopts internationally advanced structured light scanning technology, which can accurately and quickly obtain three-dimensional data of the real human foot shape.
The scanning results can be output in various popular file formats to CAD software to generate digital models. The system uses a mechanical turntable control system with closed-loop control, having a volume equivalent to four coins in size, capable of simultaneously controlling 200 servos, with a minimum control accuracy of 0.03 degrees.
The system supports full-weight-bearing and semi-weight-bearing sole scanning. It replaces time-consuming plaster casting and non-standard manual scanning with digital scanning technology, creating digital foot shape and last databases from the scanned data.
