1. An inductive system comprising:
- an elastic element made from an elastic material with a memory state, and formed in the shape of a coil for supporting an conductive element;
an insulating coating on said elastic element; and
a conductive coating formed on said insulative coating forming an inductive element;
said insulating coating extending over said elastic element with ends of said elastic element exposed for making electrical connections; and
wherein said elastic element is responsive to heat for altering its shape and the inductive value of said inductive element.

Abstract
A variable inductor is made from two elements separated by an insulating layer. The first element is elastic and serves as a coil shaped support for the inductive element. This elastic element is made with a memory and can be made to change its size by the application of heat. The inductive element is formed over the coil shaped support by layering a thin layer of a highly conductive material such as gold over the insulator layered on the elastic element. As heat is applied to the coil or as an electric current is applied to the elastic element, the size of the coil shaped support is changed which changes the inductive value of the inductive element formed by the conductive layer.

10. An inductive system used in a tuned circuit comprising:
-
an elastic material having a memory state, made in the shape of an inductive coil having two ends;
an insulating coating applied over said elastic material;
with said two ends of said elastic material exposed for making an electrical connection;
a conductive material applied over said insulating material for forming an inductor;
said elastic material made from a conductive material for carrying a current between said two ends for heating said elastic material and for changing its shape and the inductive value of said conductive material; and
said conductive material being made of a material having a greater conductivity then the elastic material which maintains its internal resistance and the Q of the tuned circuit, substantially the same in response to said heating of said elastic material. - View Dependent Claims (11, 12, 13, 14)
