Abstract
A wireless sensor platform design and a single walled carbon nanotube/ionic liquid-based chemidosimeter system can incorporated into a highly sensitive and selective chemical hazard badge that can dosimetrically detect an analyte down to a sub parts-per-million concentration.
Claims2
A device for detecting a stimulus comprising:
- a radio frequency identification tag including a sensor portion including:
- an integrated circuit;
- and
- a chemiresistor,
- wherein the integrated circuit and the chemiresistor are connected in parallel,
- wherein the sensor portion is configured to change resistivity when the radio frequency identification tag contacts or interacts with the stimulus, whereby the resistivity change alters an output of the radio frequency identification tag, and wherein the sensor portion is configured to activate the circuit or deactivate the circuit when contacted or having interacted with the stimulus.
