A stretchable liquid metal coaxial phase shifter comprising opposingly located attachment disks which are attached to opposingly located shield interface rings which are open ended cylinders defining an interior space and exterior surface.

Stretchable liquid metal coaxial phase shifter

In various embodiments, an apparatus can comprise one or more sliding mass cantilever devices. Cantilever devices can be structured as monolithic integrated structures with a mass coupled to a cantilever beam, where the mass has one or more cavities in which a liquid or solid particles are disposed. A cap can be arranged on the mass to prevent the liquid or solid particles from exiting the cavities in which they are embedded. The cantilever devices can be structured as microelectromechanical system (MEMS) resonators with a tunable resonant frequency. Such cantilever devices can be implemented as energy harvesting devices.

Microelectromechanical system resonators

Frequency bandwidth of a cantilever beam system can be enhanced using a movable mass having motion in a cavity of a mass attached to cantilever beam, where the motion is transverse to the cantilever beam. In various embodiments, a cantilever beam apparatus includes a cantilever beam, a first mass, and a second mass. The first mass can be attached to the cantilever beam, with the first mass having a cavity arranged transverse to the cantilever beam. The second mass can be disposed in the cavity such that the second mass is movable in the cavity in a direction transverse to the cantilever beam. Apparatus, systems, and methods associated with enhanced frequency bandwidth of cantilever beam using transverse movable mass are applicable in a variety of applications.
