An inertial micro-switch with multi-threshold acceleration detection capability has been proposed, taking advantage of electromechanical coupling behavior. A mathematical model behavior was established to display the dependence highly sensitivity on pull-in characteristic and show ability detect threshold by controlling voltage applied micro-switch. The that described in implemented occur at sw...

Vibrio cholerae is a human pathogen that causes mild to severe diarrheal illnesses and has major public health significance.

In this paper, the effect of the crack on dynamic behavior of cracked micro-beam in the presence of DC and AC loads are investigated. By applying the residual axial stress and fringing field stress, a nonlinear analytical model of cracked micro-beam is presented and crack is modeled by a massless rotational spring. The governing equation of the system is solved using Galerkin procedure and shoo...

A thermally tuneable, wide FSR switch, based on integrated-optic micro-ring resonators is described. This wavelength-selective switch allows high ON/OFF ratios combined with small dimensions. Furthermore allows the structure for a wide Free Spectral Range, since multiple resonators are used. This switch can be used in WDM filter arrays for a transceiver in an access network. Measurements of the...

Degradation of gold contacts in micro-switches was studied under an extensive range of operation conditions including high-electric-field ac/dc hot switching, low-electric-field hot switching and cold switching. Tests were conducted in a unique experimental switching operation set-up. Gold micro-contacts were characterized by an atomic force microscope. It was found that a unique material trans...

1. Abstract A well designed capacitive micro-machined switch requires small electrostatic pull-in force to easy switch-on and high natural frequencies to fast switch-off. Since the change of geometrical parameters of the bridge (moving part of the switch) affects contrary to one of these aspects, one could search for a shape of the bridge to obtain optimum functioning. The paper deals with desi...

A novel 2 x 2 free-space fibre-optic switch has been fabricated using surface-micromachining technology The switch IS monolithically patterned on the Si substrate. With this approach. the switch can be made compact, light weight and low ca t . In addition. i t is potentially integrable with olher micro-oplsal elements and interface electronics. The switch is attractive for fibre-optic local are...
