A fiber optic sensor employs a central support structure and at least two flexural discs spaced apart from one another along a central axis. Radially-inner portions of the flexural discs are rigidly attached to the central support structure. A fiber optic coil is affixed to one of the flexural discs. At least one proof mass is disposed between the flexural discs. Coupling means rigidly connects together radially outer edge portions of the flexural discs and rigidly connects the at least one proof mass to such outer edge portions. The flexibility of the axially-aligned outer-edge-connected flexural disc arrangement, together with the outer-edge-connected proof mass, provide for a relatively large response to axial forces.

A slot antenna where the inner CPW trace is migrated to the inside of the slot, rather than being external to the slot, and thus inverts the polarity of the center trace and puts the CPW feed section inside (within) the slot structure itself. Therefore, in this novel embodiment, the CPW feed does not increase the net size of the antenna, and results in a much smaller and/or compact design. In this fashion, now both the outer conducting surface and the CPW trace are connected and both negative (ground) polarity, whereas the tuning element is positive polarity. Thus the inner CPW trace becomes the same polarity as the outer ground conducting surface. This design is compact, without compromising an excessive amount of ground plane structure.
