A modified tuning element for a Littrow external cavity laser is demonstrated using microelectromechanical systems technology. The device combines a vertically etched blazed grating, a compound flexure suspension and drive elements for translating and rotating the grating. Tuning is linearized by linking the grating to a remote actuator by a flexible linkage. A simple theoretical model of the l...

The singular parabolic problem ut = ∆u − λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions, models the dynamic deflection of an elastic membrane in a simple electrostatic Micro-Electromechanical System (MEMS) device. In this paper, we analyze and estimate the quenching time of the elastic membrane in terms of the applied voltage —represented here by λ. As a byproduct, w...

We present the first piezoelectrically modulated resistive switching device based on piezotronic ZnO nanowire (NW), through which the write/read access of the memory cell is programmed via electromechanical modulation. Adjusted by the strain-induced polarization charges created at the semiconductor/metal interface under externally applied deformation by the piezoelectric effect, the resistive s...

Nanowires have attracted considerable interest as the nanoscale interconnects and as the moving elements of both electronic and electromechanical devices. The evaluation of nanomechanical property plays a significant role in the development of new nanowire-based devices. Recently, we are engaged in developing an easy method for nanomechanical measurement by using an in-plane-mode piezoresistive...

In this work, we have developed a design environment to allow casual users to quickly and easily create custom robots. A drag-and-drop graphical interface allows users to intuitively assemble electromechanical systems from a library of predesigned parametrized components. A script-based infrastructure encapsulates and automatically composes mechanical, electrical, and software subsystems based ...

This paper presents a micro electrostatic vibration-to-electricity energy converter based on the micro-electromechanical system. For the 3.3 V supply voltage and 1 cm chip area constraints, optimal design parameters were found from theoretical calculation and Simulink simulation. In the current design, the output power is 200 lW/cm for the optimal load of 8 MW. The device was fabricated in a si...

Optical systems are being developed to reach the functionality and large-scale integration of electronic systems. Strides are being made to develop an on-chip optical system by designing and fabricating an Optical NanoElectroMechanical, ONEM, device structure based in a gallium arsenide material system. Gallium arsenide, a III-V compound semiconductor, was chosen due to its high-refractive inde...

Hydraulic systems, as power source and transmission, offer many advantages over electromechanical or purely mechanical counterparts in terms of power density, flexibility and portability. Many hydraulic systems require touching and contacting the physical environments; and many of these systems are directly controlled by human. If hydraulic systems are passive, they would be safer to interact w...

This paper proposes a new electromechanical energy conversion system, called Field Modulated Magnetic Screw (FMMS) as a high force density linear actuator for artificial heart. This device is based on the concept of magnetic screw and linear magnetic gear. The proposed FMMS consists of three parts with the outer and inner carrying the radially magnetized helically permanent-magnet (PM), and the...
