In this paper we present a method to mitigate the effect of thermally-induced noise in Micro-Electro-Mechanical Systems (MEMS) through a force feedback circuit. Inherent noise-induced vibrations, which would be inconsiderable in macro scale, are considered as a limitation in micro- and ... Mehr lesen
微纳尺度器件在芯片散热等应用中正面临严峻的传热挑战，因此需要研究材料在不同外场作用下的传热特性。本研究以 MEMS 结构为基础，构建了一种能够实现电压调控应变场的模型，以探索应变对材料热物性的影响。 我们设计了具有梳齿结构的 MEMS 模型，并在 COMSOL Multiphysics 中利用结构力学模块与 AC/DC 模块针对应变场调控进行多物理场耦合仿真（图1）。通过施加电压控制梳齿间的静电力，使器件产生应变场。由于结构复杂，直接解析计算较为困难，因此采用载荷递增法模拟不同电压下的应变分布。仿真结果表明，当电压达到约 200 V 时，梳齿结构产生约 ... Mehr lesen
Particle In Cell (PIC) simulation tool for the simulation of 2.45GHz ECR ion source was developed tanks to Comsol Multiphysics RF module capability to compute electromagnetic field propagation imposing a tensorial permittivity with real and complex parts. A tensorial description is ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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). ...

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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
