Abstract

A device, including a non-radioactive detection source, configured to detect airborne particulates and/or gases in an environment by applying a voltage bias to the non-radioactive detection source to create at least one detecting condition, and determining if airborne particulates are present within the at least one detection condition. A method of creating a detecting condition for airborne particulates and/or gases in an environment, the method including the steps of coupling a pair of electrical conductors to a nanocellular material, and applying a voltage bias to the pair of electrical conductors.

Claims (26)

1. A device configured to detect airborne particulates in an environment, the device comprising:

a non-radioactive detection source disposed in a housing, the non-radioactive detection source comprising a pair of electrical conductors operably coupled to a nanocellular material, wherein the pair of electrical conductors apply a voltage bias to the non-radioactive detection source to cause the nanocellular material to emit light;

a light sensor configured to detect the light that is emitted from the nanocellular material; and

a processor in communication with the non-radioactive detection source and the light sensor, wherein the processor is configured to determine, based at least in part on the light detected by the light sensor, whether airborne particulates and/or gasses are present.

2. The device of claim 1 , wherein the nanocellular material comprises an aerogel.

3. The device of claim 2 , wherein the aerogel comprises a silicon-based aerogel, wherein the silicon-based aerogel is chosen from a group consisting of: a silicon carbide aerogel and a silicon oxy-carbide aerogel.

4. The device of claim 1 , wherein one of the pair of electrical conductors is operably coupled to a surface of the nanocellular material.

5. A method of detecting airborne particulates in an environment using a device including a light sensor and a non-radioactive detection source in communication with a processor, wherein the non-radioactive detection source comprises a pair of electrical conductors operably coupled to a nanocellular material, the method comprising:

(a) applying a voltage bias, by the pair of electrical conductors, to the non-radioactive detection source to create at least one detecting condition, wherein the at least one detection condition includes a photoelectric condition, wherein the creating of the photoelectric condition includes the voltage bias, provided by the pair of electrical conductors, causing the nanocellular material to emit a light, wherein the light sensor is configured to detect light that is emitted from the nanocellular material; and

(b) determining if airborne particulates and/or gasses are present within the at least one detection condition, wherein the determining is based at least in part on the light detected by the light sensor.

6. The method of claim 5 , further comprising:

(c) producing a signal if it is determined that airborne particulates and/or gasses are present within the at least one detection condition.

7. The method of claim 5 , wherein the nanocellular material comprises an aerogel.

8. The method of claim 7 , wherein the aerogel comprises a silicon-based aerogel, wherein the silicon-based aerogel is chosen from a group consisting of: a silicon carbide aerogel and a silicon oxy-carbide aerogel.

9. The method of claim 5 , wherein the voltage is equal to approximately 500 volts.

10. The method of claim 5 , wherein one of the pair electrical conductors is operably coupled to a surface of the nanocellular material.

11. The method of claim 5 , wherein the at least one detecting condition further includes an ionization condition.

12. A method of creating a detecting condition for airborne particulates in an environment, the method comprising the steps:

(a) coupling a pair of electrical conductors to a nanocellular material;

(b) applying a voltage bias by the pair of electrical conductors to the nanocellular material, wherein the voltage bias applied by the pair of electrical conductors to the nanocellular material causes the nanocellular material to emit a light;

(c) detecting, by a light sensor, the light that is emitted from the nanocellular material; and

(d) determining if airborne particulates and/or gasses are present within the at least one detection condition, wherein the determining is based at least in part on the light detected by the light sensor.

13. The method of claim 12 , wherein the nanocellular material comprises a silicon-based aerogel.

14. The method of claim 13 , wherein the silicon-based aerogel is chosen from a group consisting of: a silicon carbide aerogel and a silicon oxy-carbide aerogel.

15. The method of claim 12 , wherein the voltage bias is equal to approximately 500 volts DC.

16. The method of claim 12 , wherein one of the pair of electrical conductors is operably coupled to a surface of the nanocellular material.
