Abstract
Tunable polymer-based sonic structures ('TuPSS') are made up of sonic structures and polymers. The TuPSS has three general requirements: a) The sonic structure is composed of one or materials engineered to behave as a lens, filter, cloak, or dampener; b) Stimulus sensitive polymer is incorporated into the sonic structure; and c) The actuation of the polymer tunes the acoustic behavior of the structure in a predictable manner. The tunable polymer-based sonic structures utilize stimuli-driven physical properties of the polymers in these acoustic structures to produce a stimulus driven, or tunable, sonic structure or device. The sonic structures actively modulate mechanical vibrations that propagate through the structures, but are passive in that they do not produce mechanical vibrations. The stimuli for the structures include electric, magnetic, electromagnetic, chemical, thermal, and shaking/orientation.
