WIRELESS VOCS GAS SENSING DEVICE BASED ON ENERGY METAMATERIAL AND BREATHALYZER

Alcohol meter performance improvement wireless organic compound gas detection sensor

This technology relates to a wireless organic compound gas detection sensor based on energy harvesting metamaterials, and relates to a gas detection sensor that can overcome limiting factors such as restrictions on gas detection space and limits of detectable concentration, and an alcohol meter using the same.

There was a problem where portability was poor due to limited space to detect exposed gases, and it was difficult to use sensors in environments where trace amounts of harmful gases were exposed, and to overcome this, this technology proposes a wireless organic compound gas detection sensor method based on energy harvesting metamaterials that can overcome limiting factors.

Since this technology can overcome factors such as gas detection space limitations, manufacturing cost and process limitations, and detectable concentration limits, it can be applied to wireless organic compound gas detection sensors and alcohol meters to improve performance.

Key features:

• Receives RF (radio frequency) radio waves composed of metamaterials and stored as electrical energy
• It is provided on one side of the energy harvesting metamaterials section and contains ionic electrolytes as a sensing film
• Gas detection where the electrical properties of the sensing film change due to the interaction between the sensor film and organic compound gas
• It is arranged on the other side of the energy harvesting metamaterials unit and transmits energy harvesting data that changes according to the electrical characteristics of the sensing film
