With his students, he was a recipient of the Best Paper Award in some flagship conferences including Transducers, IEEE MEMS, and IEEE Sensors. He also currently serves as the associate editor of some flagship journals such as IEEE J-MEMS, NPG Microsystems & Nanoengineering.
Abstract
China’s Aerospace engineering has obtained fast development in the recent years. While, the MEMS technology owns the advantage of small size, low cost, etc. So, it will perfectly fulfill the requirements of aerospace applications. This talk will introduce some recent progress on the MEMS applications in aerospace engineering at NPU. The first part is the revolution to the skin of the airplane by the MEMS technology. With integrating sensing, actuating, anti-icing, energy harvesting into the wing enabled by the MEMS technology, the airplanes can fly in a different way. For example, the flexible hot film sensors were successfully developed for steady and unsteady turbulent boundary layer separation measurement of ARJ21-700 aircraft. Another example, we integrated anti-icing function to the skin based on a special bamboo growing in the Qin ling Mountains which is covered with snow and ice for five months in a year. The bamboo leaf has a unique characteristic of ice and snow phobic. The second part is the revolution to the motion sensing of the airplanes by the MEMS technology. We developed a new sensing paradigm based on serial or parallel connection of micromechanical resonators to increase the accuracy and robustness of MEMS inertial sensors for aerospace. Last, the talk will introduce some health care technologies for the astronauts, including micro flow cytometry & Chip LC.
