Abstract

A positive variable resistive yarn having a core, a sheath, and an insulator. The sheath includes distinct electrical conductors intermixed within a thermal expansive low conductive matrix. As the temperature of the yarn increases, the resistance of the sheath increases.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A temperature dependent electrically resistance yarn comprising: 
 a core yarn;    a sheath having a positive temperature coefficient of resistance, said sheath including: 
 a matrix material  
 a plurality of distinct electrical conductors intermixed throughout the matrix.
