Selection from among competing alternatives is pursued in this work for a rapidly growing class of compliant mechanisms. By using the framework of storage and retrieval of a database, we present a method to select a displacement-amplifying compliant mechanism (DaCM) for a given application. The motivation for this work is to catalogue known compliant mechanisms and thereby select the most suitable mechanism for given quantitative speci cations of the user. The quantitative data for a DaCM includes force, displacement, and stiffness speci cations at the input and the output. The DaCMs in our catalogue consist of slender beams con- gured in particular topologies. These are analyzed using nite element analysis (FEA) and the mechanism's springs-mass lever model (SML) parameters are extracted and stored parametrically as functions of the size of the device. Thus, by using the speci cations of the user, pre-computed parametric SML model parameters are utilized to select the most suitable DaCMs of appropriate size
