Abstract
A sensing system for a target includes a member with an embedded charge, at least one input electrode, at least one output electrode, at least one common electrode, one or more probes, an input system, and an output monitoring system. The input and output electrodes are spaced from and on substantially opposing sides of the member from the common electrode. At least one of the member and the input and output electrodes is movable with respect to the other. The probes which engage with the target hazardous substance are connected to the at least one of the member and the input and output electrodes which is movable with respect to the other. The input system is coupled between the at least one input electrode and the at least one output electrode and provides an input signal. The output monitoring system is coupled between the at least one output electrode and the at least one common electrode and detects a change in an output signal when the target engages with the movable member or electrode.
