In this paper, we present a miniature detection system, which is able to detect and selectively recognize different vapor traces of explosives. It is based on surface-functionalized array of COMB capacitive sensors and extremely low noise integrated electronics. The measurement system is sensitive and selective, consumes minimum amount of energy, is very small and cheap to produce in large quantities, and is insensitive to environmental influences. Owing to extremely low noise electronics and…
