From page 95...
... For example, films sensitive to pH could be macle. Measuring a certain parameter on a small cheap sensor is only half of the desired total functionality.

... This particular sensor is clesigned to detect gaseous species, but it could be constructed to detect liquids as well. The optical fiber has a thin layer of reflective materials, often a metal, deposited onto the encl.
