Pressure sensitive material color change.

Commercially available sensor films indicate pressure by changing the intensity of just one color. The pressure sensitive paint is based off the sensitivity of certain luminescent molecules to the presence of oxygen. A color changing pressure sensitive elastic material 15 sep 15 chemical engineers at stanford university have created a color changing pressure sensitive elastic material that mimics the skin of reptiles. Touching the new electronic skin e skin with varying amounts of pressure causes it to change colors as the pressure indirectly alters the chemical structure and subsequently the optical.

Through a process called oxygen quenching the fluorescence of the molecules change based upon oxygen pressure. In the case the softer the denser of color and the thicker of the materials will be used less in amount. The application amount of every thermochromic materials depends on the softness color density thickness color screening effect and color being screened effect of the materials. The system consists of an illumination source to excite the molecules a photodetector and then of course the paint.

Red patches will appear on the film when pressure is applied and the color density changes according to the various pressure levels. There are seven types of prescale available to fulfil your varying pressure range.
