Special Issue Information

Dear Colleagues,

MEMS devices have endless advantages over macrodevices and traditional electromechanical devices, with sizes ranging from micrometers to millimeters. MEMS devices are generally produced by implementing micromachining techniques inherited from the integrated circuit industry of silicon technology. From the inception of microelectromechanical systems (MEMS), multiple devices have been developed. Some have passed the development stage and reached commercialization; the first MEMS devices were commercialized in early 1980, when MEMS pressure sensors and accelerometers were widely applied in the automotive industry, and in 1995, the possibility of miniaturization of chemical analysis was introduced. MEMS devices and applications have achieved significant advances in multiple areas that have a positive impact on the technology’s application, as well as in the manufacturing processes that make them a reality. Accordingly, this Special Issue seeks to showcase research papers, communications, and review articles that focus on the following area: (1) designs and modeling of novel MEMS devices; (2) new developments and emergent applications for MEMS devices; and (3) advances in MEMS fabrication processes.

This work investigates the primary and secondary resonances of an electrostatically excited double-clamped microbeam and its feasibility to be used for sensing applications. The sensor design can be excited directly in the vicinity of the primary and secondary resonances. This excitation mechanism would portray certain nonlinear phenomena and it would certainly lead in increasing the sensitivity of the device. To achieve this, a nonlinear beam model describing transverse deflection based on the Euler–Bernoulli beam theory was utilized. Then, a reduced-order model (ROM) considering all geometric and electrical nonlinearities was derived. Three different techniques involving time domain, fast Fourier transforms (FFTs), and frequency domain (FRCs) were used to examine the appearance of subharmonic resonance of order of one-half under various excitation waveforms. The results show that higher forcing levels and lower damping are required to activate this resonance. We note that as the forcing increases, the size of the instability region grows fast and the size of the unstable region increases rapidly. This, in fact, is an ideal place for designing bifurcation inertia MEMS sensors. Full article
