Abstract
A coated article includes microsensor elements incorporated on a surface or embedded in a body, which elements are adapted to detect target chemical and/or target environmental conditions. The microsensor elements can be applied with liquid and dry mixtures, including compounds of inks, dyes, print powders, aerosols and other suspensions.
Claims6
A physical article adapted with chemical detection capability based on integrated chemical detection elements, comprising:
- a first body portion of the article;
- the chemical detection elements being incorporated on a surface of said first body portion;
- each of the chemical detection elements comprising a single integrated circuit on which is situated:
- a sensor element configured with a sensor state responsive to the presence of a target chemical when exposed to a target environment;
- a transducer coupled to the sensor element and configured to detect said sensor state and generate an output corresponding thereto;
- a magnetoelectronic (ME) processing element coupled to said transducer and adapted to perform a first sequence of operations during an operational mode on said output from said transducer;
- wherein a detection output is generated by the ME processing element having a detection value based on said first sequence of operations confirming the presence of said target chemical;
- a readout substance situated in a storage chamber of said single semiconductor chip;
- one or more micromechanical structures responsive to said detection output, and adapted to cause said first readout substance to be released from said chamber in response to said detection value;
- wherein a presence of said target chemical can be determined by detecting said first readout substance released from said chamber.
