In a previous presentation, our team has succeeded in creating an algae-bacteria symbiosis that can glow sustainably. With its blue fluorescence, the system can help search and rescue teams quickly locate people in distress at night. After brainstorming by our team, we finally decided to make the algal bacteria system into freeze-dried bacteria powder--which can be used in life jackets, parachutes, spacesuits, space capsule biomarkers and even more scenarios.
This product is a combination of innovative technology and safety concept of fluorescent positioning life jacket, designed for Marine operators and water sports enthusiasts. In the event of a shipwreck or emergency, the fluorescent positioning life jacket can quickly respond to environmental changes, and the built-in freeze-dried bacterial powder package emits blue fluorescence when activated by water, significantly improving the rescue positioning efficiency and winning valuable survival time for those in distress.
