Mechanical and Control-Oriented Design of a Monolithic Piezoelectric Microgripper Using a New Topological Optimization Method

Multiphysics field analysis and evolutionary optimization: Design of an electro-thermo-elastic microactuator

“…More recently, however, the techniques of actuation most performing in terms of position control fall in three categories: piezoelectric, thermal or magnetic actuation, respectively [3] and [8]. In the paper, reference is made to a thermally actuated device because it is a clear example of a multiphysics domain which asks for a coupledfield model.…”

“…In turn, in [2] a shape optimization of comb drive electrostatic actuators, in order to achieve prescribed driving force profiles, is proposed. In [3] the magnetic field in a permanent-magnet spherical motor at no-load is recovered, after inverting the magnetic induction measured along an accessible surface; the final aim is to compute the on-load torque by means of the Lorentz's law.…”

Biogeography-inspired multiobjective optimization for helping MEMS synthesis

“…For instance, in [10] a topology optimisation method to design a piezoelectrically-driven microgripper is proposed: four design criteria are considered, and the two-dimensional Pareto fronts trading off various pairs of criteria are identified by means of a genetic algorithm. A different approach to a similar subject was investigated in [11].…”

Design and Characterization of In-Plane Piezoelectric Microactuators

“…Level set methods [16,17] offer versatility, but are difficult to implement and computationally expensive. Numerical methods based on building blocks [18], although fast, are limited to basic geometries, while interval techniques require an analytical model of the host structure [19]. Under certain hypotheses of isotropy and simple geometries, SIMP-based methods (Solid Isotropic Material with Penalisation) [20][21][22][23][24][25] are more suitable.…”
