Abstract This work presents an automatic threshold shock-sensing trigger system that consists of a bi-stable triboelectric transducer and levitation-based electrostatic mechanism. The mechanism is sensitive to mechanical shocks releases impact energy when the shock strong enough. A generator produces voltage it receives shock. proportional When exceed certain level, initially pulled-in microele...

Effects of uncertainties in gas damping models, geometry and mechanical properties on the dynamics of micro-electro-mechanical systems (MEMS) capacitive switch are studied. A sample of typical capacitive switches has been fabricated and characterized at Purdue University. High-fidelity simulations of gas damping on planar microbeams are developed and verified under relevant conditions. This and...

Micro-Electro-Mechanical System (MEMS) is one of the few commercial platforms for building optical switches. 2D MEMS L-switching matrix has been introduced recently to double the sizes of 2D MEMS crossbar switches. The sizes of switches are mainly limited by the Gaussian signal loss associated path difference. Though the design of L-switching matrix improves system scalability but it suffers in...

MEMS optical switch technology is one of the key technologies in Wavelength Division Multiplexing (WDM) optical networks. Although the 2-D MEMS optical switch technology is mature, the commonly used crossbar architecture is not amenable to building large switches. In this paper, we propose a design of 2 × 2 switching modules, and use it to build large 2-D MEMS optical switches with architecture...

The development of new surfaces, highly sticky and conducting, is a great challenge in the field microdevices fabrication, more precisely for 3D assembly microcomponents. Such surfaces were prepared by electrochemical deposition polyaniline films. films from phosphoric acid solution adhesive than ones obtained other acids. Indeed, adhesion H3PO4 was found to be high (> 1 µN) stable time, as sho...

Current super-resolution structured illumination microscopes (SR-SIM) utilize relatively expensive electro-optic components and free-space optics, resulting in large setups. Moreover, high power laser sources are required to compensate for the losses associated with generating pattern by diffractive optics. Here, we present a highly compact flexible 2D SR-SIM microscope based on all-fiber optic...
