Abstract
Electrical devices having tunable electrical characteristics are provided, such as variable resistors, capacitors and inductors. The tunable electrical characteristics are achieved by placing an appropriate material between substrate layers and by controllably applying a pressure to the material to compress the material or alter the shape of a well in which the material is contained, and thereby alter the electrical characteristics of the electrical device. The composition, shape and dimension of the embedded materials determine how the electrical characteristics of the electrical device are altered upon compression of the embedded material in response to an applied control signal. Generally, as the embedded material is compressed, the material will become more dense and the electrical characteristics of the integrated electrical device is altered.
