Pressurex is a unique, affordable and easy to use tool that reveals the distribution and magnitude of pressure between any two contacting surfaces.
Pressurexis a mylar based film that contains a layer of tiny microcapsules. The application of force upon the film causes the microcapsules to rupture, producing an instantaneous and permanent high resolution “topographical” image of pressure variation across the contact area.
Simply place Pressurexpressure indicating sensor film between any two surfaces that touch, mate or impact. Apply pressure, remove it and immediately the film reveals the pressure distribution profile that occurred between the two surfaces. Conceptually similar to Litmus paper, the color intensity of Pressurex is directly related to the amount of pressure applied to it. The greater the pressure, the more intense the color.
Pressurex is extremely thin (4 to 8 mils) which enables it to conform to curved surfaces. It is ideal for invasive intolerant environments and tight spaces not accessible to conventional electronic transducers.

Example Usage of Pressurex Film Placed Between a Wrist Joint |
Have you ever needed to evaluate pressure or force between two touching or mating surfaces? Previously, your only alternatives were strain gauges and load cells, that are both time consuming and difficult to interface. Now with the advent of our disposable one-time use pressure film, Pressurex, evaluating surface contact pressure distribution and magnitude is accurate, quick and highly economical.
