The aim of this student project is to characterize and model the mechanics of thin-film transistors on thin, flexible foil. Initially, the transistors are put either in tension, bending outwards, or in compression, bending inwards, by elastic deformation. The strain in the devices is varied by using different bending radii and/or reducing the substrate thickness, and the change in device characteristics will be monitored. In the second phase of the project, the plastic substrate is made conformable and/or stretchable by laser cutting a honeycomb mesh structure. In the first and second phase, virtual prototyping using FEM software is a preferred method to improve the mechanical design.
- Literature research to provide you with the required theoretical background.
- Characterization of thin-film transistors on thin, plastic substrates using mechanical bending tests.
- Performing laser cutting of the plastic substrates
- FEM modeling
- Participate in group meetings, provide feed-back, discuss results, and propose solutions to various challenging aspects.
- Give presentations and write a report on the project.
You are an ambitious Masters student from mechanical engineering, electronic engineering or applied physics with both scientific and practical skills. You have good communication skills in English and you are independent but also a team player.
Duration of these projects will be 6 months or more. If you are looking forward to work in a challenging atmosphere with highly skilled co-workers then send your CV to us.
