Abstract
A conductive composition is disclosed. The conductive composition comprises a thermochromic material and a conductive material dispersed in a resin. An electrical system is also disclosed which incorporates the conductive composition in combination with a power source.
Claims18
A conductive composition comprising:
- a thermochromic material and a conductive material dispersed in a resin, said thermochromic material comprises an ambient color and at least a second color, said thermochromic material being present in an amount of between 2%-75% by weight so that said ambient color changes to said second color in response to a sufficient amount of heat applied thereto.
An electrical system comprising:
- a substrate;
- conductive composition arranged on said substrate, said conductive composition including a thermochromic material and a conductive material dispersed in a resin, said thermochromic material comprises an ambient color and at least a second color, said thermochromic material being present in an amount of between 2%-75% by weight so that said ambient color changes to said second color in response to a sufficient amount of heat applied thereto;
- and a power source connected to said conductive composition whereby current can flow from said power source through said conductive composition.
