Abstract for Presentation

Functionalizing of Intelligent Flexible Electronics for Morphing Aircraft

Rapid development of flexible electronics has enabled a broad range of applications including flexible display, health monitoring, optoelectronics and soft robotics. Most of these devices work in non-planar environments such as complex curvilinear surfaces of aircrafts. We present intelligent flexible electronics with nonstretchable materials or structures for complex curvilinear surface. Firstly, Kirigami metamaterials provide a feasible way to the fabrication of conformal electronics with improved mechanical properties for novel applications such as electronic armor (E-armor) and conformal 3D antenna.[1,2] Inspired by freeform snakeskin composed of rigid scales and connective soft integument, we propose a novel soft-node-driven Kirigami E-armor as a protection to the underlying flexible electronics or soft robotics. Secondely, Under the inspiration of unprecedented sensing abilities (skin, synapse, immune system, and brain) of flying creatures, we innovatively propose an intelligent flexible sensing skin (iFlexSense) with multifunctional sensor array, data transmission, impact monitoring and artificial intelligence for aerodynamic measurement of complex surface. The iFlexSense skin that is mounted on a NACA 0012 airfoil is validated in wind tunnel test. [3] This smart skin can characterize the flow of the whole complex surface, which is imperative to perceive and improve aerodynamic performances of modern aircrafts. Finally, we further explore the effect of 3D structures on the surrounding flows under the inspiration of wind-dispersed seeds and developed a novel set of 3D electronic microfliers.[4] Techniques in mechanically guided assembly of 3D mesostructures provide access to miniature, 3D fliers optimized for such purposes. The 3D microfliers can freely fall in the air with minimal terminal velocities, for future applications such as dispersal Internet-of-Things.
