Under The Mattress Sensor Pad

Standard Mattress Sensory System

What is Body Pressure Mapping?

The BPM Body Mapping Mattress Pad is designed to measure pressure distribution and magnitude between the body and a mattress or any other contacting surface. Pressure is a key consideration for any product that requires prolonged body contact. Our BPM system is the most economical, scientific and user-friendly system for surface pressure mapping available today.

BPM Technology

BPM is matrix based tactile surface sensor that works by the principle of piezoresistance. Tiny sensing cells cover the entire surface area of our sensor “skin” allowing for discrete spot pressure analysis at any point in the contact region.

BPM captures data from a series of sensor points propagated across the body surface and assimilates the data into our software providing you with colorized pressure maps and detailed statistical reports.

Sensor Medical’s primary proposition is to o er our clients precisely what they require or need. To that end, everything we design can be completely tailored to your unique situation.
