Micro/Nano sensors (MEMS/NEMS) and network technologies in future engineering domain have been significantly developed in the last decade. Recent developments in electronics, MEMS and NEMS have asked for stretchable/super-flexible devices that can sustain harsh mechanical deformations, for advanced applications such as wearable healthcare sensors and actuators (S&A), soft robotics, and foldable devices e.g. e-paper, solar panels etc. And major challenges and opportunities associated with such technologies are focusing on using new materials and innovative fabrication process.
In this project, the aim is to create stretchable/super-flexible devices by utilizing soft functional materials, deploying original approach by exploring the novel integration methodologies and mechanisms.
The focus will be on innovative soft material printing/patterning methodologies e.g. pinning/slippery microfluidics, to achieve an integrated multilayer devices with electro-luminescent responsive stimuli polymers (materials), optical responsive materials such as liquid crystal (chemical/physical transition) and conductive polymer materials (such as ionic hydrogels, PEDOT:PSS composites etc.).
The work packages will include theory studies and simulations, material characterisation, innovative soft material processing, as well as product design engineering.
Key technologies used in research work packages are:
• Theory and Simulation: FEA (ABAQUS, ANSYS, COMSOL)
• Materials characterisation: SEM, AFM, Electrical testing Probe station, Profilometer, Ellipsometry
• MEMS/NEMS design: K-layout, AutoCAD/Inventor, Solidworks
• Micro/nano fabrication process: Lithography, soft-lithography, RIE, CVDs, printing, packaging, integration, SAM, anodization/oxidation, Sol-Gel
• Product design: product development, rapid prototyping, ergonomics, sustainability and ethics-based design.
Project is expected to involve multidisciplinary collaboration within Northumbria University, as well as external partners such as University of Edinburgh, Heriot-Watt University, MEMSstar, etc.
This project will be supervised by Dr Yifan Li.
