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.
