Damage Detection Sensor System for Aerospace and Multiple Applications

Williams M., Lewis M., Gibson T., Lane J., Ihlefeld C., National Aeronautics and Space Adminstration, US

Martha K, Williams, Ph.D., Mark E. Lewis, Tracy L. Gibson, Ph.D., John E. Lane, Ph.D. and Curtis M. Ihlefeld The damage detection sensory system is an intelligent damage detection “skin” that can be embedded into [...]

Rapid Detection of Drugs-of-abuse in Urine and Oral Fluid by Mass Spectrometry

Ng T-T, Hu B., So P-K, Yao Z., The Hong Kong Polytechnic University, HK

Drug analysis is crucial for control of drugs abuse. Conventional drug analysis typically involves preliminary screening, followed by confirmatory analysis. However, the preliminary screening has the problem of producing false positive or false negative results, [...]

Distributed Monitoring of Soil and Groundwater during In-Situ Thermal Remediation Using Fiber Optic Sensors

Alemohammad H., Azhari A., Liang R., AOMS Technologies Inc., CA

This paper is focused on the development and field deployment of a multi-parameter and distributed fiber optic sensor for monitoring of soil and groundwater during in-situ thermal remediation of contaminated brownfields. In-situ thermal remediation (ISTR) [...]

A model for an Optical Ring Microresonator towards Nanoparticle Detection

Ahmeti F., Teker K., Istanbul Sehir University, TR

Optical resonators have shown great potential as fundamental building blocks, in a wide range of photonic devices and applications including filters, optical multiplexers, logic gates, switches and sensors. A microresonator is defined by a micron-scale [...]

Gait Analysis and Classification of Restricted Knee

Tang K., Chen Xi, Wang W., Yu J., Beijing Institute of Technology, CN

This paper presents a technique of restricted knee gait analysis and classification based on electrostatic sensing, which can be applied in home nursing of patients with exercise rehabilitation. The technique is used to monitor the [...]

Biosensor prototype based on carbon nanotubes for the RF-detection and NIR-treatment of HeLa cells

Caro G., García K., Avalos J., Morell G., University of Puerto Rico, US

The World Health Organization’s Annual Report on Cancer indicates that, in 2008, 12.4 million new cases and 7.6 million deaths from cancer alone were recorded around the world. Some of the treatments for HeLa cancer [...]

A Noninvasive Fluorescent Biosensor for Transdermal Glucose

Tolosa L., Brown S., Tiangco C., Corson E., University of Maryland Baltimore County, US

Our group has been developing a painless, noninvasive method of collecting glucose spontaneously/passively diffusing through the skin. The transdermal glucose collected in this manner has a concentration in the μM range, thus we developed a [...]

Linear-Logarithmic Two-Transistor Active Pixel Sensor with Wide Dynamic Range

Jo S-H, Bae M., Choi B-S, Choi P., Choi B-S, Choi P., Shin J-K, Kyungpook National University, KR

Image sensor technology has progressed from advanced semiconductor technology. The complementary metal–oxide–semiconductor (CMOS) process offers the capability of integrating smart functions on imagers in a single chip. As CMOS technology scales down, the pixel size [...]

Optical Fiber-Top Microcavity Sensor for CO2 Detection

Wu J., Yin M-J, Taeuber K., Dani A., Guterman R., Yuan J., Zhang A.P., Tam H-Y, The Hong Kong Polytechnic University, HK

In the paper, we present a miniature fiber-optic CO2 sensor by in-situ printing of a special polymer Fabry-Pérot (FP) microcavity on the end facet of standard single-mode optical fiber. A photo-crosslinkable poly(ionic liquid)s (PILs) with [...]

Fiber-optic sensor for bacteria detection based on intensity-modulated SPR by monochromatic excitation

da Silva Arcas A., da Silva Dutra F., da Silva Arcas A., da Silva Dutra F., Barros Allil R.C.S., Werneck M.M., Federal University of Rio de Janeiro, BR

The Escherichia coli (E. coli) O157:H7 is a human pathogen of animal origin that can cause serious illness if ingested. The most common routes of E. coli contamination are drinking water, vegetables, undercooked meat, unpasteurized [...]
