Paper Abstract

We present models of two types of microsprings namely box- spring and zig-zag spring that can be used to measure the force generated by microactuators. The spring constant for both springs is calculated by FEM using ANSYS software. In these models, the effects of short beams that act as connectors in the spring structures are considered and analyzed by changing their width. Also, from the results, we find that the box spring appears more balanced than the zig- zag spring when the force is applied in the single central direction. A series of SDAs with b ox spring have been fabricated and forces of those SDAs have been calculated.
