Abstract
A biosensor for detecting particular substances biosensor comprises a piezoelectric material, an input transducer supported by the piezoelectric material to receive an input signal and propagate a corresponding acoustic wave within the piezoelectric material and an output transducer supported by the piezoelectric material to receive the acoustic wave. At least two chemically orthogonal or semi-orthogonal biolayers are supported by the piezoelectric material to receive substances to be tested and cause corresponding changes in the acoustic wave. The output transducer can transmit a corresponding output signal embodying separate channel data indicative of the substances received.
