Abstract1:

Space exploration, flying in and beyond the Earth atmosphere, encounters dynamic but often extreme operation conditions. The design of space instruments and aerial vehicles, therefore, requires comprehensive yet creative ways to ensure system’s reliability and flexibility. The employment of smart structures, systems of sentient and responsive to the environmental stimuli, offers bright potential to conquer these challenges and is revolutionizing our modern industry. Tremendous efforts are invested in intelligent structure design forfuture aerial vehicles and satellites, enabling real-timestructural health monitoring, shape morphing, and flight controlling withenhanced safety and environmental responsibility.

In this talk, two novel smart structures will be discussed. First, ionic liquid based miniature seismometers have been developed for space missions. The unique fluidic sensing structure provides high shock tolerance and installation angle independence, which enable flexible deployment where conventional seismometers cannot survive.  Furthermore, novel ionic liquid nanocomposite has been utilized to enhance the performance and harsh environment operation capability for geophysical studies of planetary bodies (e.g. Mars, Europa). Second, origami art has been employed in engineering design to produce 3D deformable structures for wearable electronics, aerial vehicles and cube satellites. Origami-enabled designs providenot only mechanical flexibility and reliability, but also the capability of embedding multiple functional devices, which makes the integrated system intelligent and adaptive. Various functionalities including sensing, energy harvesting and storage will be demonstrated.


Abstract2:

The emerging applications of IoT and personal health care provide the growth of flexible electronics. In this talk a brief survey of flexible electronics will be provide and, furthermore, a novel origami enabled electronics concept will be introduced. Origami art has been employed in engineering design to produce 3D deformable structures for wearable electronics, aerial vehicles and cube satellites. Origami-enabled designs provide not only mechanical flexibility and reliability, but also the capability of embedding multiple functional devices, which makes the integrated system intelligent and adaptive. Various functionalities including sensing, energy harvesting and storage will be demonstrated.


Abstract3:

Film Bulk Acoustic Resonators (FBAR) are widely used in RF communication applications as one of the most successful MEMS products. Furthermore, various sensors have been also developed based on FBAR. In this talk, several sensing mechanisms, devices and applications of FBAR based sensors will be discussed.


Abstract4:

MicroElectroMechanical Systems (MEMS) have been developed for at least 30 years and become a key technology for modern life. It has extremely wide applications in biomedical, communication, personal health care, robotics, IoT and so on. In this talk, the introduction and survey on the history and current status of MEMS fabrication and devices will be provided. Some important applications will also be discussed.
