Abstract
A dehydration sensor having a stable, printable, buffered-ink composition that enables one to miniaturize the detection zone and permits both buffer and indicator dye to be applied in the same area of a detection zone, without need for a conventional, large buffer pad region. The ink composition includes a weak polymeric base as its primary buffering agent.
