Abstract

Resonant sensors for environmental health risk detection are disclosed. An adhesive may include at least one meso-scale or micro-scale resonator embedded within a material that comprises at least a portion of the adhesive. The at least one meso-scale or micro-scale resonator may be formed from a composite material. Additionally, the at least one meso-scale or micro-scale resonator may include a plurality of first carbon particles configured to uniquely resonate in response to an electromagnetic ping based at least in part on a concentration level of the first carbon particles within the at least one meso-scale or micro-scale resonator.

wherein the adhesive is configured to resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and is configured to resonate at a second frequency in response to the electromagnetic ping when the material is in a second state.

2. The adhesive of claim 1 , wherein the at least one meso-scale or micro-scale resonator includes at least one split-ring resonator (SRR).

3. The adhesive of claim 1 , wherein the resonance is an electromagnetic return signal that indicates a state of the at least one meso-scale or micro-scale resonator.

4. The adhesive of claim 3 , wherein the state of the at least one meso-scale or micro-scale resonator indicates at least one of, exposure to an analyte, exposure to a bio-material, or exposure to radioactivity.

5. The adhesive of claim 3 , wherein the state of the at least one meso-scale or micro-scale resonator is correlated to indicate a maximum value of at least one of, exposure to an analyte, exposure to a bio-material, or exposure to radioactivity.

6. The adhesive of claim 3 , wherein the state includes an absorption, or an adsorption into the material.

7. The adhesive of claim 1 , wherein the adhesive is configured to indicate an extent of adsorption into the material by generating a first electromagnetic return signal in response to the electromagnetic ping, and is configured to indicate a lack of adsorption into the material by generating a second electromagnetic return signal in response to the electromagnetic ping.

8. The adhesive of claim 2 , wherein a first set of the one or more SRRs include a plurality of first carbon particles configured to uniquely resonate in response to the electromagnetic ping based at least in part on a sensed concentration level of a first analyte.

9. The adhesive of claim 8 , wherein a second set of the one or more SRRS include a plurality of second carbon particles configured to uniquely resonate in response to the electromagnetic ping based at least in part on a concentration level of a second analyte.
