Abstract
The paper describes the tests performed to determine the characteristics of four various leaf springs, as well as the evaluation of the mounting platform/chiplet motion as a function of the excitation current. For the leaf spring evaluation, a nanoindenter (Hysitron Tribo Indenter) was used. To determine the variation of the air gap as a function of the excitation current, optical microscopy as well as laser Doppler vibrometry (LDV) was applied.
