1. Mechanics, design and fabrication of 3D microfliers

Micro air vehicle (MAV) is a new generation aircraft which has shown great potential in scientific, military and mapping applications. Previous reported smallest size of MAVs is approximately 6 cm, limited by the difficulties of miniaturizing the dynamic driving, control and energy supplying systems. Kan’s recent work pushed this boundary of size to smaller than 500 um. By mimicking wind-dispersed seeds such as dandelion seeds and maple seeds, the designed three-dimensional thin-film microflier structures can freely fall in the air with extremely small terminal velocities. These microfliers can passively fly as far as hundreds of kilometers driven by the air.

2. Design and manufacture of 3D flexible and stretchable electronics

Three-dimensional microstructures possess unconventional multiphysics properties (i.e., thermal, electromagnetic, mechanical, dynamical, optical, etc.) that 2D structures don’t confer. Therefore, 3D flexible and stretchable electroncis can achieve functions which were unachievable for the conventional 2D devices, e.g., the ultrahigh stretchability of 3D stretchable electronics, the high space-utilization efficiency for 3D flexible energy storage devices, etc.
