Abstract:

In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear behavior in the range of 2 to 25 mM in the glucose solution. The sensitivity and detection limit of this fiber optic sensor are 11.4 mV/mM  and 2.5 mM, respectively.

Preliminary Development of a Fiber Optic Sensor for Measuring Bilirubin

Preliminary development of a fiber optic bilirubin sensor is described, where an unclad sensing portion is used to provide evanescent wave interaction of the transmitted light with the chemical environment. By using a wavelength corresponding to a bilirubin absorption peak, the Beer-Lambert Law can be used to relate the concentration of bilirubin surrounding the sensing portion to the amount of...

Percutaneous fiber-optic sensor for chronic glucose monitoring in vivo.

We are developing a family of fiber-optic sensors called Sencils (sensory cilia), which are disposable, minimally invasive, and can provide in vivo monitoring of various analytes for several weeks. The key element is a percutaneous optical fiber that permits reliable spectroscopic measurement of chemical reactions in a nano-engineered polymeric matrix attached to the implanted end of the fiber....

Miniaturized Fiber Optic Sensor for Measuring Intervertebral Disc Pressure

This paper reports the development of a miniature fiber optic pressure sensor system for in vitro intradiscal pressure measurements for rodents. The primary focus of this work is the design and fabrication of a sensor element with a multi-layer polymer-metal diaphragm. This diaphragm consists of a base polyimide layer (150 nm thick), a metal reflective layer (1 μm thick), and another polyimide ...
