Abstract
Abstract A polymer based circuit production method provides a polymer based circuit by exposing a surface of a polymer substrate to ultraviolet radiation resulting in an adhesion promoted polymer substrate surface. A circuit is fabricated on the polymer substrate surface and a coating material is applied to at least a portion of the adhesion promoted polymer substrate surface. A portion of the circuit fabricated on the polymer substrate surface may be encapsulated. The polymer based circuit resulting from the method includes a polymer substrate having an ultraviolet radiation treated surface, a circuit formed on the polymer substrate surface, and a coating material encapsulating at least a portion of the at least one circuit between the polymer substrate and the coating material.
