Abstract

The responses of a polymeric optical waveguide sensor and a polymer coated Lamb wave piezoelectric sensor are used to characterize the chemical interaction of an analyte with the polymer layer. Information in the sensor response about polymer swelling, pore filling, mass loading, and changes in viscoelastic properties can be used to elucidate the interaction mechanism. Additionally, using two types of sensors in a mixed array increases selectivity by providing different information about the same sample. The complementary nature of these two sensors and their response mechanisms are explored.
