Title: The potential applications of bio-inspired 3D electronic microfliers for environmental sensing


Abstract: Miniaturized, low-cost, wireless electronic devices with meteorological sensors can serve as Lagrangian tracers and provide complementary and important information for pollution sensing, environmental monitoring, storm observations, etc. We developed and examined passive structures designed for controlled, unpowered flight inspired by wind-dispersed seeds, combining fundamental studies in Lagrangian dynamics and novel soft electronics developed for biomedical applications. Controlled mechanical buckling techniques in assembly of three-dimensional (3D) mesostructures provide access to miniature, 3D fliers optimized for such purposes, in processes that align with the most sophisticated production techniques. Specifically, this talk describes a range of 3D macro-, meso- and microscale fliers produced in this manner, including those that incorporate active electronic for pollution sensing and colorimetric payloads for pH level sensing. Analytical and experimental studies, using a set of state-of-the-art techniques such as high-speed Particle Image Velocimetry (PIV) and 3D Particle Tracking Velocimetry (3D-PTV), of the aerodynamics of high-performance 3D structures establish controlled rotational kinematics and low terminal velocities. Additional examples of these new convergence concepts in fluid/solid (continuum) mechanics, soft electronics, and optical methods will be included for other potential applications.
