Patent ID: 6955787

Claim:
An integrated sensor device for use in identifying biological and chemical agents, the sensor device comprising: (a) an array of piezoelectric resonators having electrodes, each of the resonators operating in a mode selected from the group consisting of a single mode and a dual mode: (b) two or more different sensor coatings, each one disposed on one of the resonators, the sensor coatings collectively designed to differentially absorb to one or more of the biological and chemical agents for measuring orthogonal physical properties; (c) one or more heater elements, each one integrated to one of the piezoelectric resonators; (d) a control circuit for exciting the piezoelectric resonators and for measuring frequency and impedance; (e) a control circuit configured for varying the temperature of the heater elements and for measuring the temperature, frequency and impedance of the resonators at a plurality of temperatures in order to generate data for use in thermal-gravimetric analysis; and (f) means for analyzing data collected from the control circuits to identify the biological and chemical agents.
