Figure 7.

(a) Mechanical transduction spectrum of an array of eight microbeams, engineered to show avoided crossings in the thermally tuned eigenfrequencies of the microbeams. The widths of the beams were chosen such that one pair of neighboring beams would have similar eigenfrequencies. The dashed outlines indicate avoided crossings. The solid outline indicates a nonavoided crossing. (b) Simulated array of beams of increasing widths showing the shape of the fourth in-plane eigenmode, showing that the neighboring beams are also in motion due to the coupling at the anchoring points of the beams. Displacements are greatly exaggerated for clarity.
