Chemical sensor matrix

摘要: A chemical sensor matrix is provided for sensing the presence of agents by chemo-electronic means. The comprised a plurality resonators embedded in single monolithic piece piezoelectric crystal. are arranged rectangular row and column configuration including m rows n columns, each being separated from its neighboring distances such that resonant energies do not overlap. Each coated with different substance to be sensitive agent detected so when reacts agent, frequency fmn changes. bears metallic electrode stripe row, said columns column. stripes positioned on top surface crystal, bottom areas overlap registered central portions resonators. Two diode arrays periphery crystal addressing individual desired resonator can activated connecting corresponding address suitable active oscillator circuitry signal processing then interrogated sequentially change registered.
