Pressure Indicating Film

Structure of the pressure indicating film

Pressure Indicating Film is a Mylar-based sensor film that reveals the distribution and magnitude of pressure between any two contacting, mating, or impacting surfaces.

The film 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 ï¿½topographicalï¿½ image of pressure variation across the contact area.

Simply place pressure 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 the pressure indicating film is directly related to the amount of pressure applied to it.

Pressure Indicating Film 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. Table below lists the film types

How to use it

The microcapsules in the color-forming layer are broken by pressure, and the colorless dye is absorbed into the developer, causing a chemical reaction to produce a red color. The microcapsules containing the color-forming material are adjusted to varying sizes and strengths, and is coated uniformly, producing a color density that corresponds to the amount of pressure.
