The United States has developed explosives detection sensor sensitivity of one billionth

In order to study the possibility of detecting explosives, the United States Naval Laboratory recently developed a new type of small lightweight sensor, which is reportedly composed of silicon nanowires (SiN-VAPOR) arranged vertically on the porous electrode, Improve detection of IEDs. The development of this sensor undoubtedly made a great contribution to the U.S. military.

The purpose of the SiN-VAPOR project is to develop a field-deployable distributed sensor that can be installed on a mobile phone. Its three-dimensional structure, composed of vertically aligned silicon nanowires, can be integrated into cell phones for chemical detection. Researchers at the US Naval Research Laboratory hope to promote this low-power, low-cost sensor to revolutionize the detection of trace chemicals in the battlefield or airport environments.

The SiN-VAPOR sensor, which is still in its early stages of development, is one-billionth of a percent or even one trillionth of a millimeter sensitive to the detection of trace chemicals. The project manager said the technology will serve soldiers and consumers on the battlefield as soon as possible. Naval lab researchers are looking for ways to maximize SiN-VAPOR surface area to improve sensor sensitivity. In addition to this application, SiN-VAPOR sensors can also help bomb sniffer dogs to detect suspicious objects to improve the safety of the airport, it is not difficult to imagine the sensor in the future battlefield will have a breakthrough.
