Researchers from Shinshu University and Chiba University in Japan have developed an innovative bio-hybrid drone that integrates odor-sensing antennae from silkworm moths, significantly enhancing its capabilities for a range of applications such as disaster response and gas leak detection. This novel drone incorporates an electroantennography (EAG) sensor, achieving superior odor detection accuracy and extending its effective search range to up to 5 meters, compared to less than 2 meters for previous models. By mimicking the natural odor-tracking behaviors of insects through a "stepped rotation algorithm," the drone overcomes limitations faced by conventional drones, which often rely on visual sensors that can be hindered by environmental conditions. This breakthrough technology has the potential to improve rescue operations in disaster-prone areas and enhance public security by detecting hazardous substances. The findings were published in the journal npj Robotics on February 5, 2025.
