Soft Materials, Electronics and Machines
- from Tunable Surfaces to Emerging Electronics to Medical Devices
Invited by the School of Mechanical Engineering and Mechanics of Ningbo University, Prof. Changyong Cao from Departments of Packaging, Mechanical Engineering, Electrical and Computer Engineering, Michigan State University, presented a talk entitled "Soft Materials, Electronics and Machines " to a broad audience of researchers and graduate students on Dec. 25, 2018.
Prof. Cao presented some work that his laboratory has done in the field of mechanics and physics of soft materials and nanomaterials, particularly the mechanical instability of thin film-substrate system, the printed, flexible, and stretchable electronics, and the innovative biomedical devices. He first described how they used numerical and experimental methods to identify the instability modes and the scaling laws for generating tunable surfaces patterns. Then, he demonstrated how to harness mechanical instabilities and large deformations from soft materials to develop stretchable supercapacitors and novel medical devices. Finally, he showed their recent efforts in developing robust, smart and sustainable packaging system with engineered materials and technologies.
