Abstract:
The design and performance of an
in-situ
, remotely monitored pH sensor is presented. The sensor is comprised of magnetically soft thin film structure or powder combined with a polymer that swells or shrinks in response to changes in pH. The performance of several magnetostatically coupled thin film structures when subjected to an AC magnetic field is discussed.
