Fiber Sensor Offers Real-Time Hydrogen Sulfide Monitoring for Industrial Safety

A new fiber-based electronic device using modified metal-organic frameworks detects hydrogen sulfide gas and generates power, with potential for affordable industrial safety applications.

Researchers at Korea Institute of Materials Science, Pusan National University, and Korea Aerospace University developed a fiber-based electronic device that generates electricity and detects hydrogen sulfide gas. The device uses modified UiO-66 metal-organic frameworks with fluoro and amino groups. It achieves 7.16% power conversion efficiency—representing approximately 29% improvement over conventional titanium dioxide photoelectrodes—and detects hydrogen sulfide within about 9 seconds. The device maintains 80% of its initial performance after 1,500 bending cycles and 20 washing cycles. Published in the *Chemical Engineering Journal* on August 13, 2026, this technology could enable real-time hydrogen sulfide monitoring in industrial settings, potentially preventing poisoning incidents. Future work will focus on expanding gas sensing applications through additional metal-organic framework materials.
