摘要:
Described herein is an approach using inexpensive, disposable chemical sensor probes that can be mounted on a small unmanned aerial vehicles (UAVs) and used to analyze a site (such as one known or suspected to contain explosive residue, spilled material or contaminated soil) without the need for a person to conduct ground operations at the site. The method involves contacting a soil or a surface with a filter paper wetted with a solvent, then subjecting the filter paper to voltammetry and/or spectroscopy, thus detecting a possible variation indicative of one or more analytes, wherein the solvent is selected from the group consisting of polar aprotic or protic solvents having a boiling point of at least 100° C., room temperature ionic liquids, and deep eutectic solvents.

The present invention is directed to a method for making a conformal antenna on a surface by providing a composition comprising a polymer matrix and a plurality of metalized tubules and applying the composition to the surface as two parallel wires connected at their ends to make a closed loop with one of the parallel wires broken in the middle. Also disclosed is an alternate method for making a conformal antenna on a surface by spraying a first material comprising a polymer matrix onto the surface and simultaneously spraying a second material comprising a plurality of metalized tubules and a coagulant onto the surface, wherein the first and second materials mix together during the spraying. A further method for making a conformal antenna includes spraying a first material comprising a polymer matrix and a plurality of metalized tubules onto the surface and simultaneously spraying a second material comprising an aqueous electroless plating bath onto the surface, wherein the first and second materials mix together during the spraying.

The present invention is generally directed to an artificial dielectric composite having an electrically non-conducting substrate, an electrically non-conducting pattern on the substrate, and an electrically conducting coating on the pattern. The substrate may be a textile such as paper. The electrically non-conducting pattern may comprise palladium. A direct-write device, such as an inkjet printer, may be used to print the pattern onto the substrate. The electrically conducing coating may comprise nickel, gold, palladium, cobalt, iron, copper, or any combination thereof. Also disclosed is the related method of making the artificial dielectric composite.
