Micromechanical cantilevers show great potential as highly sensitive biochemical sensors. Cantilever-based sensing involves the transduction of a biomolecular interaction to a measurable mechanical change in the cantilever resulting from induced surface stresses added mass. In surface stress sensing applications, one side of the cantilever beam is rendered sensitive to a specific target molecul...

Cantilever fixed partial dentures are defined as having one or more abutments at one end of the prosthesis while the other end is unsupported. Much controversy without documentary evidence has surrounded this prosthesis. Despite negative arguments, the cantilever prosthesis has been used extensively by the clinicians. If used nonjudiciously without following proper guidelines these might lead t...

The precast segmental bridge has the advantages of fast construction speed, good economic performance, and small impact on surrounding environment. In order to study role temporary pre-stressing system in cantilever assembly process segment box girder bridge, ABAQUS was used simulate standard section a viaduct. Studying compressive stress relative sliding joint under action self-weight pre-stre...

Thanks to the cantilever launching technique, arch bridge building has once again become popular throughout world. Today, these structures are one of three main types long-span bridges, along with suspension and cable-stayed bridges. Arch have a complex behavior during powerful earthquakes because rib is an element that primarily susceptible large axial compression force brought on by dead load...

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 μm x 100 μm x 1 μm SiO2 cantilever integrated with 0.2 μm thick Si piezoresistor was used in this study. The sensor performance was measured on the basis of displacement sensitivity and surface stress...

We investigate the possibility of an electromechanical which–path interferometer, in which electrons travelling through an Aharonov–Bohm ring incorporating a quantum dot in one of the arms are dephased by an interaction with the fundamental flexural mode of a radio frequency cantilever. The cantilever is positioned so that its tip lies just above the dot and a bias is applied so that an electri...

This article describes tapping mode atomic force microscopy (AFM) using a heated AFM cantilever. The electrical and thermal responses of the cantilever were investigated while the cantilever oscillated in free space or was in intermittent contact with a surface. The cantilever oscillates at its mechanical resonant frequency, 70.36 kHz, which is much faster than its thermal time constant of 300 ...
