Abstract
A system includes an array of chemical, pressure, and temperature sensors, and a temporal airflow modulator configured to provide sniffed vapors in a temporally-modulated sequence through a plurality of different air paths across multiple sensor locations.
Claims14
A system for machine olfaction comprising:
- a sensing unit comprising an array of chemical, pressure and temperature sensors,
- wherein the chemical sensors are temperature controlled and produce trace data over time responsive to plumes of an analyte introduced to the sensing unit,
- wherein the pressure sensors produce pressure data over time responsive to the plumes of the analyte introduced to the sensing unit,
- wherein the temperature sensors produce temperature data over time responsive to the plumes of the analyte introduced to the sensing unit;
- and
- a computer configured to provide power to the array of chemical, pressure and temperature sensors, and to wirelessly transmit trace data, pressure data, and temperature data from the array of chemical, pressure and temperature sensors to a host computer to produce chemical, pressure and temperature time series data specific to the analyte.
