Designs of micro electro-mechanical devices need to be robust against fluctuations in mass production. Computer experiments with tens of parameters are used to explore the behavior of the system, and to compute sensitivity measures as expectations over the input distribution. Monte Carlo methods are a simple approach to estimate these integrals, but they are infeasible when the models are compu...
In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...
Due to transistor leakage, CMOS circuits have a well-defined lower limit on their achievable energy efficiency [1]. Once this limit is reached, power-constrained applications will face a cap on their maximum throughput independent of their level of parallelism. Avoiding this roadblock requires an alternate switching device with steeper sub-threshold slope—i.e., lower VDD/Ion for the same Ion/Io...
In this paper, an Adaptive Neuro Fuzzy Inference System (ANFIS) based control is proposed for the tracking of a Micro-Electro Mechanical Systems (MEMS) gyroscope sensor. The ANFIS is used to train parameters of the controller for tracking a desired trajectory. Numerical simulations for a MEMS gyroscope are looked into to check the effectiveness of the ANFIS control scheme. It proves that the sy...
We study the dynamics of a resonantly driven nonlinear resonator (primary) that is nonlinearly coupled to non-resonantly linear (secondary) with relatively short decay time. Due its relaxation time, secondary adiabatically tracks primary and modifies response. Our model, which motivated by experimental studies on interaction between nano- micro-resonators, simple can be analyzed analytically nu...
For the lack of formula of linear range for S-shaped MEMS planar micro-spring, this paper establishes physical and mathematical model and analysis the material stress-strain angle. The formula is deduced by calculating the strain and rotation of the basic unit of micro-spring tension. Compared with the results of the tests on micro-spring which produced by UV-LIGA process, the formula results i...
