Electronic Devices and Systems


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.

NeuroConnect 2026 | Organoid Neurophysiology Workshop
26.03.2026 | Karlsruhe

Prof. Dr. Jasmin Aghassi-Hagmann is co-organizing the upcoming Workshop NeuroConnect 2026:

To find better treatments for brain disorders, we aim to develop enhanced in vitro models of the human brain and mature them through electrical stimulation. A 1-day workshop with international experts and the local scientific community in the Rhine valley in Freiburg and Karlsruhe on 26 March 2026 will kickstart this research direction.

KIT and Intel Develop Microchip for Research-oriented Teaching

KIT is the first German university to develop a test chip together with the semiconductor manufacturer Intel.

Students and researchers at the Karlsruhe Institute of Technology (KIT), together with the US chip manufacturer Intel, have developed a microchip designed for research and teaching - starting from the design process to tape-out and eventually raw die characterization. The chip is called KIT “Callisto” with a total area of four square millimeters and exploits Intel 16 which is Intel’s CMOS Finfet-16nm transistor technology.
