Aerosol microsensor

A sensor comprising:

• a sensing oscillator comprising a component configured to change in oscillation frequency in response to an aerosol particle, liquid-borne analyte, and/or chemical vapor attaching, depositing, and/or interacting with an outer surface of the component, wherein the sensing oscillator is less than about two inches long;
• a reference oscillator configured to act as a timing reference for the sensing oscillator;
• an environmental sensor;
• a communication medium configured to transfer data from the sensing oscillator, the reference oscillator, and/or the environmental sensor to an external source;
• and
• a microcontroller coupled to the sensing oscillator, the reference oscillator, the environmental sensor, and/or the communication medium.
