ULTRA-FAST RESPONSIVE COMPOSITE SENSOR USING GEL AND CRISTALIZED PARTICLES AND METHOD OF MANUFACTURING THE SAME

High-speed VOC detection, real-time color change composite sensor

This technology is about a sensor that can visualize the detection of the target object in color, and is about a complex sensor and manufacturing method that can expect rapid detection by using the characteristics of a gel that changes in volume when exposed.

Existing volatile organic compound (VOC) detection methods have limitations such as long measurement times, large equipment, and high costs, making real-time analysis difficult.

This technology is a complex sensor that uses gel-crystallized particles to quickly detect VOCs through color changes. It has a response speed up to 3,000 times faster than existing methods, and enables real-time on-site monitoring through intuitive color changes. It is intended to provide a simple, quick and inexpensive sensor that can be used to check health factors or detect environmental changes.

Key Features:

• The principle of changing the visible color by changing the distance between colloidal particles due to volume change and changing the wavelength of reflected light
• Forming a colloidal crystal structure of the desired shape using a hydrophilic/hydrophobic pattern or inkjet printing method on a substrate
• Coating the formed colloidal crystal structure with a flexible component (e.g. polydimethylsiloxane, PDMS) that can absorb VOCs
• The presence of VOCs is detected by immediate color change Convenient to use because it can be detected
