Each electrode pellet is set into the bore of the HydroCel Hydrating Skin Interface
Chamber, a soft, plastic pedestal (Figure 2-6).
If the HCGSN has sponge inserts, then each electrode is surrounded by a sponge that
is wetted with liquid electrolyte during operation. With this Net, the wetted sponge
protrudes slightly from the one end of the pedestal and the lead wire emerges from
the base of the electrode pellet.
By definition, a sensor (Figure 2-7) consists of a pedestal and an electrode.
Cutting the pedestal assembly of the sensor down the middle makes its construction
easier to see (Figure 2-8).
