At the same time, many practical issued associated with the use of optical oxygen sensors in food packs still remain. These have to be addressed to adapt the existing sensing materials and prototype systems for real-life applications, achieve the required sensor specifications, operational performance and safety. Considerable technological developments and effort in eliminating current problems and bottlenecks are required, to facilitate widespread use of the oxygen sensors by food and packaging industry.

Because of the experience gained in the Burro Series experiments, the downwind gas concentration sensor arrays were modified. This was based on the facts that beyond 400 m from the spill point the very low concentrations made the sensors of limited value and that close to the spill point, water and mud thrown up by RPT explosions had adverse effects on the sensors. Most of the open-path IR sensors for the measurement of LNG concentration were positioned at multiple levels on the downwind arrays between 140 and 400 m. In addition, some alternative sensors from International Sensor Technology and Mine Safety Appliance for measuring concentration were installed. 

Nowadays the chemical sensors are widely used for chemical monitoring in ecology, industry to diagnose substances and materials to provide safety of technological processes and facilities to control food s and goods quality in medicine and other fields (Fig.3). 

Aerospace applications require a range of sensor technology to enable improved performance, increased safety, better awareness of the vehicle health state, and to enable increased automation and autonomy [3]. The following are three examples of aerospace applications involving the detection of gas species one associated with space propulsimi and fuel safety, one related to aircraft emissions monitoring, and the third involves both space and aircraft fire detection. Briefly described is each application as well as the shortcomings of traditional technology.

Copper, zinc, and titanium nanostractures are promising materials to be used in food safety and technology. The antimicrobial properties of above metals at the nanoscale provide affordable and safe innovative antimicrobial strategies (Table 2). Copper has been shown to be an efficient sensor for humidity, while titanium oxide has resistance to abrasion and UV-blocking performance. The migration of cations from the polymer matrices is the key point to determine their antimicrobial effectiveness, however, this migration of cations may affect the legal status of the polymer as a food contact material. 

Opportunities exist using currently available data fusion and sensor technology to mitigate these problems and reduce the severity of and even eliminate their effects, increasing marine safety in general and specifically the safety of navigation. 

Critical safety devices will be substatially improved withbetter sensors, more measurements, new technologies, and more reliability for critical and shutdowns ... 

The Fido technology is currently under evaluation for use by U.S. military forces. The Fido X and Fido XT are available as commercial off-the-shelf (COTS) items. Consequently, the technology is adequately mature for commercial deployment. However, as a platform technology, the AFP sensor and Fido detection system support broad application to meet explosives detection needs. Further, Nomadics has incorporated the amplification features of AFP into other sensor mechanisms aimed at the detection of analytes that are not explosives related, including other chemicals and compounds of interest in the biomedical and food safety fields. Thus, while the technology is mature enough for commercialization, its potential is far from fully exploited.
