Health and safety has always been a concern for the general public. Recently security and surveillance, typically of interest to governments and military, have also become important to this broader audience. Deployable, miniature, low power sensor platforms (SP) which integrate sensor subsystems with support- subsystems (power, wireless and internet communication and processing) are highly attractive to provide a large array of sensing capabilities for these applications. While the support subsystems are important, they are largely complete, while the chemical sensor subsystems are still vastly under-developed. For sensors to generate information worthy of communicating for protection applications, they must sequentially evolve from information gathering to problem identification, decision making, and even actuation. Such advanced sensor platforms would be integral to the high value process of protecting and enabling people.
