Abstract
A biosensor detection system for detecting a particular substance has at least two biosensor devices. Each biosensor device includes a piezoelectric material, an input transducer mounted on the piezoelectric material to receive an input radio frequency signal and propagate a corresponding acoustic wave within the piezoelectric material and an output transducer mounted on the piezoelectric material to receive the acoustic wave and transmit a corresponding output radio frequency signal. A biolayer is mounted on the piezoelectric material to receive a substance to be tested and cause a corresponding change in the acoustic wave. An oscillator circuit is connected to the input transducer and to the output transducer, the oscillator circuit including an amplifier and providing an output signal indicative of a change in the acoustic wave. The biosensor devices having two different biolayers, whereby the output signals can be utilized to detect receipt of a particular substance by the biolayers of the biosensor devices.
