Antheraea Polyphemus with complex antennae

Researchers at the Oak Ridge National Lab and the Georgia Institute of Technology have recently published their studies on the natural olfaction structure of male moth antennas that could serve to improve performance of preconcentrators for chemical sensing. They analyzed the natural dimensions and the hierarchical structure of the antenna design and fabricated a 1:1 scale replica of the moth antenna using Nanoscribe’s two-photon polymerization based 3D printer. The antenna structure consists of suspending features with a three level hierarchy of branching at the micro scale. Through this study, the antenna branch geometry and angle measurements as well as the 3D microprinting fabrication of the synthetic replica allow to create a novel preconcentrator for sensing substances faster than typical gas sensors. The 3D printed antenna could be used for odor collection analysis and in future applications for sensing explosives or drugs.
