[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 difference...
[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 the...
[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 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 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: 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...
[Illinois] Engineering the Mode Coupling in Microrings for Laser and Sensor Applications
12 Feb 2016 | | Contributor(s):: Lynford Goddard
The integrated microring Bragg reflector forms the basis of a new family of compact reflective photonic devices. The buildup of field strength in the high quality factor ring resonator configuration yields multiple reflection encounters with the same set of gratings. This enables high...
