Pressure Sensitive Material Color Change

In the case the softer the denser of color and the thicker of the materials will be used less in amount.

Pressure sensitive material color change. 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. 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. 0 05 300 mpa 7 25 psi 43 500 psi. 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.

Red patches will appear on the film when pressure is applied and the color density changes according to the various pressure levels. Commercially available sensor films indicate pressure by changing the intensity of just one color. Through a process called oxygen quenching the fluorescence of the molecules change based upon oxygen pressure. The system consists of an illumination source to excite the molecules a photodetector and then of course the paint.

Our sensor films can be painted on the contact surfaces so that the color variance in different areas clearly shows the stress distribution over the contact surface yin explained. The e skin an electrochromic fabric changes its color and overall appearance with touch and surrounding conditions.
