Used to measure the contact pressure distribution on a contact surface, the system, featuring stable performance, precise measurement, and a high number of measurement points, can display the contact pressure of the entire contact surface as 2D and 3D pressure distribution images, and record the entire force application process as a video file.

Through a simple calibration function, it can obtain the magnitude, time, and location of the force and pressure acting on the sensor.

WORKING PRINCIPLE

The sensor consists of an array of piezoresistive sensing units based on flexible polyimide (PI) film. This film material is soft and has excellent mechanical durability. When each sensing unit is subjected to pressure, its

internal conductive structure forms a circuit, causing the resistance value to change with pressure. The system collects the resistance signals of each unit in real-time and, combined with array topology and calibration data, analyzes the pressure distribution map of the contact area, enabling high-resolution measurement of pressure magnitude, location, and distribution pattern.

Meanwhile, the software supports flexible switching between various international standard mechanical units such as kg/cm², kPa, and PSI, and allows one-click export of raw data in TXT/CSV formats for subsequent processing and archiving

Intelligent Area Analysis and Process Playback

The software provides powerful intelligent area analysis functions, allowing users to flexibly customize analysis areas according to testing requirements. The system will automatically calculate and output key parameters for each partition per frame of data, such as average pressure, maximum/minimum pressure values, and contact area. Furthermore, the test process recording function can completely capture data throughout the entire testing cycle and supports quick playback and precise positioning via an intuitive timeline, which enable you to easily trace back to any critical pressure change node, meeting the needs of in-depth analytical research.

Intuitive Multi - dimensional Data Visualization

To transform data into intuitive insights, the software offers 2D/3D pressure cloud visualization solutions, using industry-standard color gradients to clearly map pressure levels. Simultaneously, the system can automatically generate pressure vs. time curves, clearly presenting dynamic data history, and supports overlay comparative analysis of multi-channel data, providing you with comprehensive, graphical insights from static distribution to dynamic changes.

Professional Report Generation and In-depth Data Analysis

The software supports user-customized analysis reports and a comprehensive library of body pressure distribution metrics. It can automatically calculate the following:Overall Metrics: Total pressure, Average pressure, Maximum pressure, Pressure standard deviation.Area Metrics: Total contact area, Contact area percentage.Balance Metrics: Pressure center (center of gravity) coordinates and trajectory, Left/right and front/rear balance ratios.Regional Metrics: Average pressure, Maximum pressure, and Load percentage for each partition.Users can flexibly select these metrics, combine them with pressure cloud maps and curve charts, to quickly generate

professional analysis reports in various formats with clear conclusions. This thoroughly resolves the challenges of data interpretation and results presentation, significantly enhancing research, development, and evaluation efficiency.
