This paper reports the theoretical investigation of the strain sensitive effect of a 2D photonic crystal (PhC) nanocavity resonator for mechanical sensing applications. By using finite element method (FEM) using ANSYS software and finite different time domain (FDTD) simulation using CrystalWave software, the strain sensitivity of high quality factor PhC nanocavity have been studied. Linear relationships...
This paper describes the design, microfabrication and characterization of a 0.35 ??m CMOS compatible multi-terminal pressure sensor (MTPS) with on-chip biasing circuit. This sensor is an alternative to the pressure sensors based on the conventional silicon Wheatstone piezoresistive bridge (WB) or four terminal piezotransducers. The layout of the MTPS is designed in such a way that the sensor sensitivity...
This paper uses finite element method to obtain the optimal performance of piezoresistive microcantilever sensor by optimizing the geometrical dimension of both cantilever and piezoresistor. A 250 mum times 100 mum times 1 mum SiO2 cantilever integrated with 0.2 mum thick Si piezoresistor was used in this study. The sensor performance was measured on the basis of displacement sensitivity and surface...
Numerous researchers have already been involved in for designing, driving and optimizing RTWUSM, such as the control model of the whole USM system, the no-load speed, the maximum output power, the characteristic about torque to the frequency, etc. USM has been widely manufactured for civil use in Japan, military using in USA and Germany, and other uses in many European and Asia country. But fewer...
The purpose of this paper is to answer a basic problem of finite element method that is how do the elements which have determined shapes form the element grid which has determined structure. In order to study this problem, a method called chain-making and chain-coupling is established. Through this method the qualified relationships between the geometric structures of the element grid and the geometric...
Starting from effects on machining quality that vibration acts on silicon wafer, we know the importance of the control of wire-vibration in wafer cutting. Based the analysis of the system, the paper builds up Hamiltom principle system models, and analyzes it with the finite element method. Different parameters on the natural frequency results are given. Finally, this paper presents the active control...
