Binary mixture quantification using cell-based odor biosensor system with active sensing

Portable cell-based biosensor system using integrated CMOS cell-cartridges.

The use of cell-based biosensors outside of the laboratory has been limited due to many issues including preparation of the sample, maintenance of the biological environment, and integration of the electronics for data collection and analysis. This paper describes a system that addresses several of these issues with the development of an integrated silicon-polydimethylsiloxane cell-cartridge. T...

Meat and Fish Freshness Inspection System Based on Odor Sensing

We propose a method for building a simple electronic nose based on commercially available sensors used to sniff in the market and identify spoiled/contaminated meat stocked for sale in butcher shops. Using a metal oxide semiconductor-based electronic nose, we measured the smell signature from two of the most common meat foods (beef and fish) stored at room temperature. Food samples were divided...

Motion Based Bird Sensing Using Frame Differencing and Gaussian Mixture

Background segmentation is a general technique that aims at detecting the moving objects in a sequence of continuous scenes or video stream by separating the non-moving background from the moving foreground object. The success and weakness of a foreground and/or background segmentation method depends on several external factors such as the scene selection, lighting, and weather conditions. Henc...

A Novel Cell-Based Hybrid Acoustic Wave Biosensor with Impedimetric Sensing Capabilities

A novel multiparametric biosensor system based on living cells will be presented. The biosensor system includes two biosensing techniques on a single device: resonant frequency measurements and electric cell-substrate impedance sensing (ECIS). The multiparametric sensor system is based on the innovative use of the upper electrode of a quartz crystal microbalance (QCM) resonator as working elect...
