Predictable behaviour is a critical factor when developing a sensor for potential deployment within a wireless sensor network (WSN). The work presented here details the fabrication and performance of an optical chemical sensor for gaseous acetic acid analysis, which was constructed using inkjet printed deposition of a colorimetric chemical sensor. The chemical sensor comprised a pH indicator dy...

An electronic nose composed of small, inexpensive chemical sensors would have many potential applications in areas such as breath analysis, hazardous gas detection and industrial process monitoring. An electronic nose, in anology to a biological nose, consists of an array of non-specific chemical sensors. With pattern recognition, the system can recognize individual chemicals or scents. Capacit...

There are only a handful reports about the sensor systems having the ability of detecting the existence of the noble gases. Chemical reluctance of these gaseous species causes them to have no chemical interactions like hydrogen bonding with the chemically designed nano-sized sensors. Noble gasses usually have no atomic charges nor do change the total polarity of the molecular sensor systems. Th...

Introduction The electrochemical gas sensor project is now at a state were the results of the first test pointed out the different needs for improvement and optimization both of the fabrication process and the testing. This report will focus on this sensor, detail the obtained results for CO sensing, and list the different feedbacks obtained. All those information will help building a second ge...
