Preparation and characterization of electrospun nickel oxide/polymer fibrous electrodes for electrochemical capacitor

Tsutsumi H., Hosogai S., Yamaguchi University, JP

Electrospinning provides a simple and unique technique for preparation of fibers with the diameters ranging from the nano- to microscale. We prepared the electrospun fiber which contains nickel oxide (NiO) as the electrochemical active material [...]

RF-MEMS Voltage Tunable Capacitor using Electrostatic Forces

Lee J., Kim Y., Na D., Park S., Kyungpook National University, KR

In this paper, we have proposed a fabrication method of a RF-MEMS voltage tunable capacitor using Au-electroplating technique, which has one movable parallel plate with various structure of beams. We applied an electrostatic method and [...]

Comparative Studies of Novel Capacitive Transducers with Non-Planar Diaphragms

Chen J., Liu L., Li Z., Liu L., Tsinghua University, CN

Novel single-chip fabricated condenser structures with corrugated diaphragms for residual stress releasing have been proposed and simulated. An electrostatic-structural coupling FEM analysis has been performed to fully reveal the nonlinear relationship of output electrical signal [...]

Electro-Mechanical Transducer for MEMS Analysis in ANSYS

Gyimesi M., Ostergaard D., ANSYS, Inc., US

The paper introduces an electro-mechanical transducer finite element (EMT) for the strongly coupled simulation of micro electro-mechanical system (MEMS) devices in the commercial finite element analysis (FEA) package ANSYS.
