Shorya Awtar's Doctoral Research. Alexander Slocum and conducts research in a variety of areas including nanotechnology, MEMS, machine-tool design, bearing link, to name a few. This page provides a detailed description of these projects.

Most work shorya awtar phd thesis ku this page is either patented or published. This work presents a new class of parallel-kinematics flexure mechanisms that have multiple degrees of phd thesis and substantially small error motions.

Global navigation

These mechanisms are of importance to macro and micro scale precision positioning applications, including MEMS sensors and actuators, optical imaging, and semiconductor shorya awtar phd. A systematic approach for the analysis and synthesis of these shorya awtar phd thesis ku mechanisms is presented.

Synthesis rules are explored based on fundamental phd thesis principles such as symmetry and reciprocity. An attempt is made to quantify the effects of these intuitive design rules. Constraint analysis, error motion analysis, and performance optimization are some of the areas that are explored for a specific shorya awtar phd thesis ku awtar of flexures, and may /purchase-an-essay-describing-yourself.html extended to other topologies as well.

Here is a link to a mechanism more info Thesis came up with while designing my experimental set-up.

I could not find a good mechanism to hold in-plane capacitance probes, that are used for highly accurate measurement shorya awtar phd thesis ku small displacements. Please send me a note if you know of any similar or other in-plane probe holders.

Most existing diaphragm flexures are prone to parasitic error motions, i. A symmetric diaphragm flexure that is free of such parasitic motions is presented. Read more on this basic flexure design, some interesting torque couplings and linear shorya awtar phd thesis ku are developed.

Synthesis and analysis of parallel Kinematic XY flexure mechanisms

The following invention disclosure provides a detailed discussion, and pertinent prior art. Two axis thesis MEMS mirrors find use in many applications including raster scanning, image projection, optical networking, bio-medical imaging, etc.

In all shorya awtar phd applications micro-mirrors are employed to steer a beam of light. While successive single axis mirrors may be used to steer the beam along multiple axes, a single two-axis mirror provides a shorya awtar phd thesis ku, more compact and inexpensive alternative. Departing from the prior art, we conceived a two-axis optical scanning mirror design based on a novel resonant structure that provides optimal raster scanning action.

The two scanning axes click the following article orthogonal and are designed to be highly decoupled. Furthermore, translational errors of the mirror are eliminated by using the principle of virtual pivot for cantilever beams. PZT electrodes are thesis to excite the structure at the frequencies that correspond to its two shorya awtar phd thesis ku natural vibration modes.
