Bifurcation-enhanced ultrahigh sensitivity of a buckled cantilever
Buckling, first introduced by Euler in 1744 [Euler L (1744) Opera Omnia I 24:231], a sudden mechanical sideways deflection of a structural member under compressive stress, represents a bifurcation in the solution to the equations of static equilibrium. Although it has been investigated in diverse research areas, such a common nonlinear phenomenon may be useful to devise a unique mechanical sens...
متن کاملSimulation of a Buckled Cantilever Plate with Thermal Bimorph Actuators
INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the performance of a range of MEMS devices by decreasing any unwanted coupling effects or parasitic losses from the dev...
متن کاملUHeater on a Buckled Cantilever Plate for Gas Sensor Applications
Introduction: In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. As a consequence of this surface interaction, charge transfer takes place between the absorbed species and the sensitive material. The change of the concentration of the free charge carriers is translated into a change of th...
متن کاملSensitivity of an Atomic Force Microscope Cantilever with a Crack
The atomic force microscope (AFM) has become an essential tool for the measurement of surface characteristics of diverse materials on a microand nanoscale level [1]. The resolution of measurements for the AFM cantilever is related to its vibration sensitivity. Many researchers have much interest in studying the resonant frequency and sensitivity analysis of AFM cantilevers [2 4]. Cracks may be ...
متن کاملSensitivity analysis of a caliper formed atomic force microscope cantilever based on a modified couple stress theory
A relationship based on the modified couple stress theory is developed to investigate the flexural sensitivity of an atomic force microscope (AFM) with assembled cantilever probe (ACP). This ACP comprises a horizontal cantilever, two vertical extensions and two tips located at the free ends of the extensions which form a caliper. An approximate solution to the flexural vibration problem is obta...
