Claim:
1. A flexible heater, comprising: a flexible conductive base fabric extending from a first edge portion to a second edge portion opposite the first edge portion; a first electrical terminal extending along the first edge portion from a first end to a second end opposite the first end, the first electrical terminal electrically coupled to the base fabric at a first seam, the first seam including a stitched coupling of the first electrical terminal to the first edge portion with electrically conductive thread; a second electrical terminal extending along the second edge portion from a first end to a second end opposite the first end, the second electrical terminal electrically coupled to the base fabric at a second seam, the second seam including a stitched coupling of the second electrical terminal to the second edge portion with electrically conductive thread; and a first thermal layer applied proximate the first and second edge portions, the first thermal layer covering the first and second seams, the first thermal layer including a heat resistant elastomer, and wherein the semi-conductive polymer is polypyrrole.
