Enabling Design and Manufacturing for Flexible Hybrid Electronics
Flexible hybrid electronics is a kind of integrated solution which aims to remain the processing function and performance of traditional integrated circuits while realizing the advantages of flexible electronics. Its fabrication process should be compatible with microelectronics technology and printing process. This report mainly introduces the design method and manufacturing principle of flexible hybrid electronics.
1）Delicate structure design of flexible hybrid electronics: Self-similar fractal structure, conformal analysis for non-stretchable materials on curved surface, buckling of serpentine structures under pressure and tensile, etc. These theories can determine the characteristics of tensile deformation, surface conformal, deformation stability and so on.
2）High-resolution electrohydrodynamic (EHD) printing: EHD printing has the drop-on-demand printing, near-field direct-writing, electrospray atomization and other printing modes, which can realize additive manufacturing and EHD lithography of submicron structures. It has been used in the fabrication of ultra-stretched piezoelectric sensors, ultra-thin touch screens, and so on.
3）Laser lift-off technology for ultra-thin flexible electronics: The mechanism model of laser-material interaction at peeling-PI interface is established. A laser lift-off technology for fabricating high-process temperature piezoelectric sensor on low temperature substrates is proposed. And it can realize the lift-off of 1-μm-thick flexible electronics efficiently.
4）Innovative applications. Briefly introduce flexible electronics in human physiology information collection (Epidermal electronics), various physical measurements of aircraft surfaces (smart skin), and other applications in other fields.
