Body Pressure Measurement System (BPMS) – Research
Body Pressure Measurement System
BPMS™ measures the pressure distribution of a human body on support surfaces such as seats, mattresses, cushions, and backrests. The thin and conforming sensing mat can measure body pressure distribution with minimal interference of the support surface.
Key Benefits
-
Design optimization
- Verify comfort
- Ergonomics
- Understand body shifts in a static chair or an application with a moving vehicle – ingress/outgress
- Analyze comfort of different materials for seat design
- Quality control
- Competitive benchmarking
- Marketing tool to demonstrate the comfort of your product
- Fully conforming sensor available (CONFORMat™) avoids hammocking or measurement of artifact
Key Applications Include:
- Comfort Testing and Analysis
-
Support Surface Design
- Shape/contours of seat or backrest
- Dimensions of seat
- Firmness and padding
- Material Testing
- Durability and Longevity Studies
- Ingress/Egress Studies
- Seating and Positioning Research

BPMS Sensors
- Features spatial resolutions as fine as one sensing element per square centimeter
- Contain as many as 2,016 individual sensing elements
- Multiple mats can be used to cover a surface and provide up to 16,128 sensing elements
- Thinness enables the user to incorporate it into the application without altering the support surface
CONFORMat Sensors
- Conforms to complex, contoured, and deformable support surfaces like seat cushions
- Sensor will not capture pressure artifacts, only the loaded area
- Mat design eliminates sensor hammocking while it conforms to the surface
The BPMS system is built on a “modular” sensor construct concept. This means you can acquire a system in many ways from one pressure sensor up to eight. This allows you to grow your BPMS as your needs expand, thus protecting your initial investment.
Seating vs Mattress System Configurations
The system is comprised of data acquisition electronics, sensors, and software. BPMS™ is configured depending on the application and sensor selection which drives the amount of electronics that are needed. This system is compatible with Evolution and our Versatek electronics. Our qualified engineers will help you select the optimal system configuration to meet your application requirements.Seating
