Micro/Nano Scale Manufacturing Control

The following ARG students are currently conducting research in the field of micro/nano scale manufacturing control.


Ashley Armstrong: Dynamic Modeling and Control of a Micro Robotic Deposition System
Dynamic modeling and control of a Micro Robotic Deposition System, with bone scaffold manufacturing as the target application. In this research, precision motion control techniques will be explored to achieve the high levels of precision and response time demanded by microscale applications. Movement coordination between two additive manufacturing extrusion heads will be used to print bone scaffolds with advanced architecture.

Spencer Kieffer: Control of a Roll to Roll Electrohydrodynamic Jet (E-Jet) Printer
spencerkieffersuitInk jet printing technology is used by millions of people every day. Although it is incredibly effective for most applications, ink jet printers leave much to be desired when micro- and nano- scale feature sizes are required. E-Jet printing, a new technology that can print features orders of magnitude smaller than ink jet printers, can overcome these shortcomings. My current research is focused on developing E-Jet printing technology to print functional devices, such as circuits and biosensors, on scales smaller than can currently be achieved by any additive manufacturing technique.

Xavier Moya: 3-D Heterogeneous Functional Integration of Electronics
headshotHigh power density is desirable in most electronics applications. However, contemporary systems are limited in this regard, as traditional planar circuit boards require external cooling to manage their thermal loads. I am seeking to create devices with higher power densities by moving to a three-dimensional design with embedded thermal transport vias and cooling. My research focuses on combining heterogeneous additive manufacturing with microdevice fabrication and assembly to create compact, fully-integrated 3D electronic circuits.

Nathan Weir: Precision Motion Control
My research focuses on the development of precision motion control strategies for inertially stabilized pointing systems. Precision pointing systems are used to aim and stabilize sensitive instrument or sensor payloads for a variety of applications including photography, videography, astronomy, remote sensing, and communications. The jitter requirements for future systems grow more demanding as higher resolution sensors become available. Pointing systems that require a large field of regard and high precision are often limited in performance with conventional bearing technologies. This research seeks to advance the state of the art of precision stabilization systems through the design, analysis, and experimental evaluation of a novel hybrid flexure bearing concept to minimize the effects of nonlinear friction that typically degrade jitter performance in systems with conventional ball bearing joints.

 

Other Research Areas:

Electrohydrodynamic Jet Printing
Nano and micro-manufacturing has emerged as a critical component of nano and micro systems technology. Along with an increasing variety of available materials comes a need for increasingly sophisticated manufacturing platforms capable of utilizing said materials at higher and higher levels of resolution. Electrohydrodynamic jet (E-jet) printing uses an electric field to induce fluid flows from micro capillary nozzles to create devices in the micro/nano-scale range.The figure below  presents the basic components of an E-jet printer and the video showcases the camera view (10x) of the E-Jet printing process in real time fashion.E-Jet Schematic

E-Jet printing has emerged as a high resolution alternative to other forms of direct solution-based fabrication approaches, such as ink-jet printing. The diameter of an E-Jet Printed droplet ranges from several hundreds of nanometer up to a few microns. Depending on the application, E-Jet printer can either produce discrete droplets or continuous lines. In the past decade, there has been various application for E-Jet printing, primarily for biosensing and printed electronics application.E-Jet ApplicationJournal Publications
