Abstract:
1. A system for receiving, analyzing and communicating results of sensing chemical and/or physical parameter values, the system comprising: N sensors numbered n=1, . . . , N (N≧2), of parameters, where each sensor senses an electrical parameter value EPV(t wherein at least one NS is loaded with a selected sensitizing substance drawn from a group of sensitizing substances comprising Au particles, located between first and second ends of the at least one NS, and the first and second ends are connected to first and second terminals, respectively, of at least one of a voltage source and a current source, and to an electrical parameter value measurement mechanism that measures a change in at least one of electrical current, voltage difference, electrical resistance, electrical conductance and capacitance between the first and second ends of the at least one NS; a multiplexer, having at least N input terminals and at least one output terminal, that receives at least one of a sensed value EPV(t a wireless transmission module, connected to the multiplexer output terminal, to receive and transmit at least one of the sensed value EPV(t a computer that is programmed to receive, from the wireless transmission module, and to compare at least one of the second value EPV(t where the N sensors, the multiplexer and the wireless transmission module are contained in a volume having a diameter no greater than about 14 cm.
