Accurate measurement of impact forces is essential for understanding injury mechanisms and improving vehicle safety. Pressure distribution analysis during crash events allows engineers to evaluate how forces are transferred between contacting components and the human body surrogate. 

Sensor Products International provides pressure and force measurement solutions designed for crash test dummy and high-speed impact applications. Our technology enables the capture of temporal, spatial, localized, and peak pressures generated when two objects collide during an impact event. 

Thanks to high data acquisition rates, even extremely fast impacts can be recorded with sufficient resolution to analyze rapid force changes over time. Pressure data can be used to support the development of safer vehicle interiors and restraint systems, including dashboards, headrests, seat belts, airbags, and energy-absorbing structures. 

Flexible, thin pressure sensors are available in multiple geometries and can conform to complex or curved surfaces, making them suitable for applications such as knee impact testing and other localized contact scenarios. Measurement setups can be adapted to specific test configurations and development goals, providing reliable and repeatable results for engineering analysis.
