Abstract:
In recent years, interest in sensor networks has risen rapidly, driven mainly by the almost ubiquitous availability of wireless communications networks, the increasing power and capabilities of mobile phone platforms, and the need to exploit new sources of data (and hence revenue) beyond conventional phone calls. Phones now can be used to access, generate and exchange audio, video and photo files, and they now have an increasing array of sensors incorporated as standard (e.g., accelerometers, gyroscopes etc.). The increasing interest in new data sources is exemplified by vision statements and strategic movement of very large computing, ICT, network, mobile phone companies into sensor networks. Examples include the Nokia ‘Morf’ concept, IBM/INTEL activity in Smart Cities, and the HP ‘Cense’ vision. However, despite the enormous activity both into sensor networks and into the development of improved chemical sensors over the past decade, there has virtually no penetration of chemical sensing platforms into widely distributed sensor network deployments, although the key barriers have been repeatedly highlighted. The simple message is that current technologies for autonomous chemical sensing are still not fit for purpose, and do not meet the cost/performance requirements for inclusion in environmental deployments.
