Water-retaining hydrogel electrode stabilizes an insect-antenna odor sensor for biohybrid drones (IMAGE)
Caption
Researchers from Shinshu University and Chiba University developed a water-retaining hydrogel electrode that stabilizes the contact between an excised silkworm moth antenna and an electroantennogram (EAG) sensing system. The hydrogel helps retain moisture around the antenna–conductive gel contact, allowing the insect-antenna sensor to maintain odor responses for up to 7 hours under tested indoor, room-temperature conditions. The stabilized sensor was also mounted on a small drone, where odor-evoked signals were used to trigger forward motion.
