Welcome to the research unit of Prof. Aghassi-Hagmann in which we explore electronic devices and systems in future technologies with a special focus on printed electronics. We are an interdisciplanary group of electrical engineers, physicists, material scientists and computer scientists located at KIT campus north working on printed materials, novel nanomaterials, micro/nano-structured devices, additive manufacturing techniques and systems in the field of future electronic technologies. We strive for gaining understanding from materials to device level and to develop solutions for electronic, bioelectronic and energy applications.

If you are interested in our research or seek job oppertunities do not hesitate to contact us.
