A 15 mode piezoelectric sensor with mechanical amplification is provided. e sensor consists of two piezoelectric members mounted on an electronically inert, rigid substrate. The two members have an electronically inert amplification device connected between them. When acoustic energy passes through the two members, they develop an electric charge which results in the upper ends of the members moving away from each other. Since the lower ends are anchored in the substrate, this causes a shearing response in the members. The shearing is amplified by the attached amplification device, yielding a strong piezoelectric response. In detection mode, incoming acoustic waves cause a mechanical flex in the attached amplification device. The flex of the amplification device causes a shearing response in the two attached piezoelectric members. This shearing causes a generation of electric charge.

A contactless, multi-dimensional small stepper motor with a maximum dimension of less than about 10 centimeters is described. The motor contains at least one magnetized article, at least one superconductive primary suspending element, and at least two primary conductive elements. Each of the primary conductive elements is separated from each adjacent primary conductive element by a distance of from about 0.01 to about 10 millimeters.
