Perhaps the most widely known nonlinear phenomena in nanoand microelectromechanical systems is the “pull-in” or “jump-to-contact” instability. In this instability, when applied voltages are increased beyond a certain critical voltage there is no longer a steady-state configuration of the device where mechanical members remain separate. This instability affects the design of many devices. It may...

High resolution and noncontacted measurement tools for the dynamic characterization of micro devices are necessary to develop high performance/precision and reliable microelectromechanical systems (MEMS). In this paper, a three-dimensional dynamic measurement system based on stroboscopic and interferometric methods is presented. This system can capture bright-fielded and interferometric images ...

This paper presents for the first time a design methodology for MEMS/NEMS based on haptic sensing technologies. The software tool created as a result of this methodology will enable designers to model and interact in real time with their virtual prototype. One of the main advantages of haptic sensing is the ability to bring unusual microscopic forces back to the designer’s world. Other signific...

This research quantitatively investigates fluid damping of MEMS and NEMS flexural resonators such as scanning probe and carbon nano-tube resonators, aiming to improve the quality factor prediction and therefore the resonator design. Fluid damping in beam-type resonators is most affected by resonant frequency, device dimensions and cross-sectional shape which are systematically examined within. ...

Over the past decade, tissue engineering in the field of medicine has proven to provide alternative therapies for tissue or organ implants, especially providing a functional implantation and avoiding immune rejection of tissues and organs. [...].

Nanorobotics is currently a much studied field by the international scientific world. Numerous applications of nanorobotics make it to expand in several areas. This occurs through the integration of several disciplines, including nanofabrication processes used to produce nanorobots, nanoactuators, nano-sensors and nanometer scale physical modeling. Some of the most important applications of nan...

Microelectronics processing technology spawned a new area of science and engineering exemplified by the acronyms MEMS (microelectromechanical systems) and NEMS (nanoelectromechanical systems). Microengineering is a multidisciplinary investigation of the physics and science of the submillimeter scale world and the application of this understanding to develop mass-producible microdevices and syst...

Finite element analysis facilitates optimal design of MEMS/NEMS devices for reliability. The same is used here to analyze the effect of types of fractal rough surfaces on static response of nanobeams Three-dimensional rough surfaces are generated using modified two variable Weierstrass-Mandelbrot function with given fractal parameters. Beam with various fractal roughness are modelled to observe...
