Quasi-static 2D-MEMS vector scanners are micro-opto-electro-mechanical systems (MOEMS) made of monocrystalline silicon. The primary application for these controllable micromirrors is the high dynamic and precise deflection of laser beams, for example in light detection and ranging ... En savoir plus

The use of optical sensors in the industry is still growing. A transmission of signal from the sensors is mostly done by optical fibers. Switching the signals from optical paths may be done by using micromechanical silicon switches. The main advantage is an ability to transmit data from ... En savoir plus

Overview We successfully simulated a template iontronic system for closed-loop neuromodulation and neurosensing. The model’s goal is to support the careful design of novel platforms for in-vitro micro-electrode-array sensors coupled to conductive polymer-based (CP) ionic actuators used ... En savoir plus

Artificial muscles are materials or devices that mimic the motion of muscles and can change their shape and stiffness in response to external stimuli. We consider pneumatic soft actuators with fiber reinforcements designed to contract upon pressurization and mimic the motion of skeletal ... En savoir plus

Electric forces acting on a neutral matter in divergent electric fields generate mechanical stresses even in absence of charged species. This mechanism is invoked here as a factor in solid dielectric breakdown (BD). Closed form analysis for coaxial cylinders and point-to-plane gaps is ... En savoir plus

A new design of electrostatic comb drive actuator is presented in this paper by using different spring designs and with different folded beam lengths. An increased displacement of lateral comb drive actuator will subsequently be accomplished with the same actuation voltage. Stress ... En savoir plus

The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). ...

As reliability of transformer is highly dependable on high voltage condenser type bushing, there is need to design bushings with low dielectric stress to insure the large lifespan of components. It is analytically not possible to predict or analyze the stresses generated at foil edges, ... En savoir plus

The main purpose of SPIDER (Source for the Production of Ions of Deuterium Extracted from RF plasma) test facility is the investigation and optimization of a negative ion beam produced by the full size ion source for ITER NBIs (Neutral Beam Injectors). Thermal, transient, non-linear FE ... En savoir plus

Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... En savoir plus
