Pressure Sensitive Material Color Change

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.

Pressure sensitive material color change.

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. 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.

The pressure sensitive paint is based off the sensitivity of certain luminescent molecules to the presence of oxygen. For example they may change from a pale red to darker red. There are seven types of prescale available to fulfil your varying pressure range. 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.

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.
