This paper presents system-level modeling and simulation of force-balance MEMS comb accelerometers. The work focuses on the theoretical principles of the sense element and the interface electronics at first. Based on that, the parametric model of the sense element is established in this paper, and the simulation results of this model match well with the theoretical results, which can prove we can...
This paper focuses on the design optimization of the applications of electrothermal polysilicon microactuators with the considerations of uncertainties from mathematical models and random variables. The deflections and actuation forces in the micro-cantilevers are modeled based on experiment results; furthermore, the non-negligible errors due to extrapolations are estimated numerically. The response...
Based on the classical laminated plate theory and the piezoelectric plate and shell theory, this paper presents an analytical analysis of a circular piezoelectric actuator used in micro-systems. The actuator consists of four layers: piezoelectric ceramic, metal, electrodes and epoxy resin. Each layer has different dimensions, material properties and initial stress. For the simply supported boundary...
In the paper, a dynamic model that has two inputs (voltage and load) is presented. Nonlinearities in piezoceramics when they are subject to two inputs are classified into memory storage mechanisms and the memoryless mechanisms. A multi-layer neural network is presented in order to describe the memoryless mechanism, which represents the cross coupling effects between two inputs. A numerical form of...
