[Illinois] ECE 416 SPR Sensors II
21 May 2013 | | Contributor(s):: Brian Cunningham
In this lecture, it is a continuation of the SPR Sensors discussed in the last one. We start off with the definition of a Surface Plasmon, which is an oscillation of electrons at the interface between a good conductor and a...
[Illinois] ECE 416 Optical Sensors I
06 Mar 2013 | | Contributor(s):: Brian Cunningham
In this lecture, we begin our discussion of Optical Biosensors. We start off by showing the general properties of optical biosensors besides the SPR. Then, we shift our attention to the improvements made to the SPR Sensor's...
[Illinois] ECE 416 SPR Sensors III
05 Mar 2013 | | Contributor(s):: Brian Cunningham
In this lecture, we continued the SPR Sensors discussion. We started off with the coupling condition being determined by the refractive index. This means that light now goes through a protein. In the experimental results, it shows...
[Illinois] ECE 416 Electrochemical Sensors
27 Feb 2013 | | Contributor(s):: Brian Cunningham
In this lecture, we begin discussing the three types of electrochemical sensors: Potentiometric, Amperometric, and Conductometry. The focus of the lecture is the potentiometric and how it is used to measure the potential...
[Illinois] ECE 416 Glucose Sensor I
In this lecture, we continue the discussion on the oxygen sensor. It starts with a review of the measurement of O2 concentration levels through electrical currents. This is called an amperometric meter. Then, the subject shifts to...
[Illinois] ECE 416 Glucose Sensor II
In this lecture, we looked at the three generations of the glucose sensor and the ways it has changed. The first generation was the one discussed in the previous lecture in which the glucose concentration was found based off of...
[Illinois] ECE 416 Acoustic Wave Sensors
In this lecture, we look at the concepts and theories behind the acoustic wave sensor. This sensor communicates through the vibrational waves in matter. The atoms in the system are displaced, causing an Internal Elastic Restoring...
[Illinois] ECE 416: Biosensors
07 Feb 2013 | | Contributor(s):: Brian Cunningham
Learn the underlying engineering principles used to detect small molecules, DNA, proteins, and cells in the context of applications in diagnostic testing, pharmaceutical research, and environmental monitoring. Biosensor approaches including electrochemistry, fluorescence, acoustics, and optics...
A CNTFET-Based Nanowired Induction Two-Way Transducers
05 Sep 2012 | | Contributor(s):: Rostyslav Sklyar
A complex of the induction magnetic field two-way nanotransducers of the different physical values for both the external and implantable interfaces in a wide range of arrays are summarized. Implementation of the nanowires allows reliable transducing of the biosignals' partials and bringing of...

In Search of a Better MEMS-Switch: An Elementary theory of how nanostructured dielectrics may soften landing, increase travel range, and decrease energy dissipation
06 Jun 2012 | | Contributor(s):: Muhammad Alam
In this talk, I will discuss an elementary theory of the role of nanostructured electrodes in addressing some of the challenges from a fundamentally different perspective. The goal is to start a conversation regarding the viability of the approaches suggested and see if the perspective offered...

Illinois iOptics Lecture 5: Deposited Nanorod Films for Biosensor Applications
17 May 2010 | | Contributor(s):: Brian Cunningham
Planar photonic crystals have been used as the basis of many biological sensing devices. Here, we successfully demonstrated that the combination of a photonic crystal structure and a dielectric nanorod coating prepared by the glancing angle deposition technique can lead to significant increases...
Peanuts vs. Pyramids: Two Perspectives on MEMS
29 Dec 2009 | | Contributor(s):: Stephen D. Senturia
MEMS, the acronym for Micro-electromechanical Systems, also known simply as “Micro-systems,” come in two main types: commodity products (the peanuts) and MEMS-enabled products (the pyramids, or, more correctly, the inverted pyramids). The economics of scale greatly affect how these two classes...
