Silicon nanowires (SiNWs) fabricated by MEMS technology and its DC response to antigen (HBsAg) was demonstrated in this paper. Anisotropic self-stop etching was employed to ensure low cost batch production. Electrical characterization revealed that, field effect of such device, with SiNWs' width and thickness in the order of 10 nm, guaranteed linear resistance modulation in a wide range, which made...
A microfabricated breath sensor based on multi-walled carbon nanotubes (MWCNTs) has been designed, developed and tested. This sensor has a simple capacitor structure, including a pair of metal electrodes fabricated by micromachining, which are then coated by a layer of carbon nanotubes. This structure takes advantage of the unique electrical property of MWCNTs in the small gap space as a function...
This paper deduces a remarkably precise analytical formula for calculating the fundamental resonant frequency of V-shaped cantilevers using Rayleigh-Ritz method. This analytical formula, which is very convenient for MEMS sensor design, is then validated by ANSYS simulation. This formula raises a new perspective that, among all the V-shaped cantilevers, the simplest triangular cantilever can lead to...
It is reported that the most urgent issue for 90% of the blind is the sense of direction. Even today the blind is lack of electronic products to provide direction guide, a novel electrical blind stick system is designed in this paper, By listening to the alarm from the blind stick, the blind can judge whether they are walking on the blind road or not. This paper described the principle of the system...
In order to solve the pressure measurement problem in the harsh environment, such as high temperature above 200degC, a special piezoresistive pressure sensor chip has been developed. Based on the MEMS (micro electro-mechanical system) and SIMOX (separation by implantation of oxygen) technology, the piezoresistive pressure sensor chip was constituted by silicon substrate, a thin buried silicon dioxide...
Microelectromechanical system (MEMS) convective accelerometer based on convection heat transfer has many advantages such as simple structure, low cost and great anti-shock property. Due to its great anti-shock property, we research the output characteristics of the convective accelerometer with low measuring range (plusmn5 g) (g stands for acceleration of gravity) when the input is heavy impact (500~30,000...
