An electrostatic bifurcation-based microcantilever sensor equipped with a tip plate is investigated for sensitivity. A closed-form expression for sensitivity of this type of sensors is approximated using the frequency-response equation of the cantile

This paper investigates the postbuckling and free vibration response of geometrically imperfect multilayer nanobeams. The beam is assumed to be subjected to a pre-stress compressive load due to the manufacturing and its ends are kept at a fixed dista

This article provides criteria for the design of electrostatic arch micro-tweezers. The tweezers can be operated in two modes: a traditional quasi-static mode where a direct current voltage commands the tweezers arms along a trajectory to manipulate

We identify a new instability in electrostatic actuators dubbed quasi-static pull-in. We report experimental evidence of the instability and study its characteristics in two types of micro actuators operating in ambient air. We found that the underly

This paper introduces a tunable MEMS magnetic field sensor. It uses torsional vibrations excited by Lorentz force to measure the strength of external magnetic fields. The sensor sensitivity and dynamic range can be tuned on-the-fly by varying its dc

We report a novel electrostatic MEMS sensor to detect solutes in aqueous media. This is the first demonstration of an electrostatic sensor in aqueous media. The sensor is excited electrostatically and its response is measured capacitively. It is equi

This paper investigates the effects of thermal load and shear force on the buckling of nanobeams. Higher-order shear deformation beam theories are implemented and their predictions of the critical buckling load and post-buckled configurations are com
