Abstract:
An H2S sensor includes at least one acoustic wave transducer and a film having a polymer matrix. The polymer matrix includes carboxylate functional groups and lead or zinc cations. The film may have a thickness of between a hundred nanometres and a 2 microns The H2S sensor optionally includes an antenna to remotely interrogate the H2S sensor.
