A Dynamic Uncertainty Protocol for Digital Sensor Networks

November 1, 2021
Author(s)
Michael Gaitan, Richard A. Allen, Jon Geist, Akobuije Chijioke
We propose a concept of the use of dynamic uncertainty to improve the accuracy and robustness of digital sensor networks. The digital smart transducer is integrated with a microcontroller that reads the binary data from the calibrated sensor, performs an

CHARACTERIZATION OF LASER DOPPLER VIBROMETERS USING ACOUSTO-OPTIC MODULATORS

December 31, 2020
Author(s)
Michael Gaitan, Jon C. Geist, Benjamin J. Reschovsky, Akobuije Chijioke
We report on a new approach to characterize the performance of a laser Doppler vibrometer (LDV). The method uses two acousto-optic modulators (AOMs) to frequency shift the light from an LDV by a known quantity to create a synthetic velocity shift that is

The role of standards in MEMS commercialization

April 1, 2015
Author(s)
Michael Gaitan
For many years, the development, creation and use of standards has played a valuable role in the successful commercialization of products, services and processes that address many industries and many applications. So it is with microelectromechanical

The MEMS 5-in-1 Test Chips (Reference Materials 8096 and 8097)

March 27, 2013
Author(s)
Janet M. Cassard, Jon C. Geist, Craig D. McGray, Richard A. Allen, Muhammad Y. Afridi, Brian J. Nablo, Michael Gaitan, David G. Seiler
This paper presents an overview of the Microelectromechanical Systems (MEMS) 5-in-1 Reference Material (RM), which is a single test chip with test structures from which material and dimensional properties are obtained using five documentary standard test

The Art in Science of microTAS (Editorial)

March 12, 2013
Author(s)
Michael Gaitan
The discovery of a natural phenomenon unveils a curtain of ignorance from what has always existed. However, the creation of art requires the use of materials and knowledge combined with artistic inspiration to create a work of aesthetic appeal. By this

User's Guide for RM 8096 and 8097: The MEMS 5-in-1, 2013 Edition

February 15, 2013
Author(s)
Janet M. Cassard, Jon C. Geist, Theodore V. Vorburger, David T. Read, Michael Gaitan, David G. Seiler
The Microelectromechanical Systems (MEMS) 5-in-1 is a reference device sold as a NIST Reference Material (RM) that contains MEMS test structures on a test chip. The two RM chips (8096 and 8097) provide for both dimensional and material property

ITRS Chapter: MEMS

January 30, 2013
Author(s)
Michael Gaitan
The ITRS has organized a MEMS Technology Working Group (TWG), which has developed a new chapter on MEMS for its 2011 report. The report focuses on MEMS technologies associated with mobile Internet devices, such as smartphones and tablet computers. These

MEMS Kinematics by Super-Resolution Fluorescence Microscopy

September 27, 2012
Author(s)
Craig D. McGray, Samuel M. Stavis, Joshua Giltinan, Eric Eastman, Samara L. Firebaugh, Jenelle Piepmeier, Jon C. Geist, Michael Gaitan
Super-resolution fluorescence microscopy is used for the first time to study the nanoscale kinematics of a MEMS device in motion across a surface. A device under test is labeled with fluorescent nanoparticles that form a microscale constellation of near

The MEMS 5-in-1 Reference Materials (RM 8096 and 8097)

March 21, 2012
Author(s)
Janet M. Cassard, Jon C. Geist, Michael Gaitan, David G. Seiler
The MEMS 5-in-1 Reference Material (RM) contains test structures for five standard test methods on one test chip, so companies can compare their in-house measurements taken on the RM with NIST measurements, thereby validating their use of the documentary

DNA Molecules Descending a Nanofluidic Staircase by Entropophoresis

January 26, 2012
Author(s)
Samuel M. Stavis, Jon C. Geist, Michael Gaitan, Laurie E. Locascio, Elizabeth A. Strychalski
A complex entropy gradient for confined DNA molecules was engineered for the first time. Following the second law of thermodynamics, this enabled the directed self-transport and self-concentration of DNA molecules. This new nanofluidic method is termed

MEMS

January 12, 2012
Author(s)
Michael Gaitan
Micro-Electro-Mechanical Systems (MEMS) are devices that are fabricated using techniques similar to those used for integrated circuits (ICs) to create micrometer-sized mechanical structures (suspended bridges, cantilevers, membranes, fluid channels, etc.)

DNA ENTROPOPHORESIS: A BALANCE OF ENTROPY AND DIFFUSION IN COMPLEX NANOCONFINEMENT

October 3, 2011
Author(s)
Samuel Stavis, Jon Geist, Michael Gaitan, Laurie E. Locascio, Elizabeth Strychalski
Entropophoresis - motion caused by an entropy gradient - is a novel nanofluidic method to direct the self-transport of biopolymers that established a new paradigm of nanofluidic functionality with broad relevance to lab-on-a-chip technol-ogy. Here, the

ROADMAPPING MANUFACTURING NEEDS FOR MEMS TECHNOLOGIES

September 30, 2011
Author(s)
Michael Gaitan, Karen Lightman
This report summarizes issues in manufacturing from the 2011 iNEMI MEMS Technology Roadmap, and shares the authors’ observations from the 2011 MEMS Industry Group’s (MIG) Workshop on Device Testing and the 2012 ITRS MEMS Technology Working Group’s (TWG)

Trapping and Release of Citrate-Capped Gold Nanoparticles

August 1, 2011
Author(s)
Darwin R. Reyes-Hernandez, Geraldine I. Mijares, Brian J. Nablo, Kimberly A. Briggman, Michael Gaitan
An electrical method to trap and release charged gold nanoparticles on and from the surface of alkanethiol self-assembled-monolayer (SAM) modified gold electrodes is presented. Gold nanoparticle (GNP) coated electrodes were formed by immersing amine
