Micro-mirror arrays are currently being developed by a number of companies for optical switching. To bring these products to the market quickly, a rapid development cycle is needed, leaving little time for multiple fabrication runs. CAD tools for MEMS can reduce the number of fabrication iterations run by allowing prototyping to occur within the virtual environment. Here, many models can be tes...

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...

This paper presents an analytical modeling of a piezoelectric multi-layer cantilever used as a micro-electro-mechanical-system (MEMS) chemical sensor. Selectively coated microcantilevers have been developed for highly sensitive chemical sensor applications. The proposed piezoelectric chemical sensor consists of an array of multi-layer piezoelectric cantilevers with voltage output in the millivo...

We study phonon-mediated dissipation mechanisms in small-scale mechanical systems in light of recent efforts to design high-Q micrometerand nanometer-scale electro-mechanical systems (MEMS and NEMS). We consider dissipation mechanisms which redistribute the energy within a resonator, such as thermoelastic damping, the Akhiezer effect, and the Landau–Rumer effect, as well as the radiation of ene...

Piezoelectricity in ferroelectrics arises from electrostriction biased by their spontaneous polarisation, which can be enhanced through a bias-induced polarisation. Doing so, the piezoelectric response tuned and significantly enhanced. In this study, ferroelectric polymer P(VDF-TrFE) was used to electro-mechanically excite silicon microcantilever. Using device, we demonstrate that polarisation ...

Structural health monitoring (SHM) is an essential aspect to ensure the safety and longevity of civil infrastructure. In recent years, there has been a growing interest in developing SHM systems based on Micro-Electro-Mechanical Systems (MEMS) technology. MEMS-based sensors are small, low-power, cost-effective, making them ideal for large-scale deployment structural systems. However, use can be...

The case study presented in this paper is a demonstration of our mixed-signal, multi-domain system level simulation tool Chatoyant. We have developed Chatoyant to support modeling and simulating of microopto-electro-mechanical systems. In this paper we demonstrate the capabilities of Chatoyant to model and simulate an RF MEMS shunt switch. We perform a system level simulation of the RF switch a...

The field of microfluidics has seen breath-taking progress since its beginnings in the 1980s and early 1990s. While much of the initial work was a by-product of mainstream micro-electro-mechanical systems (MEMS) and silicon based fabrication schemes, soon a specialized research field developed. Over the last decade a strong, highly interdisciplinary microfluidics community emerged with roots in...

For the testing of micro electro-mechanical systems, we propose a taxonomy built-in self-testing methods. These solutions that are non-intrusive, cost-effective and typically non-intrusive during process being actively sought after as cost micro-electro-mechanical systems (MEMS) can account for 50% total end product. The selection methods is analyzed extensively, classification table such prese...
