Joint Workshop "Origami Science and Engineering"

Since 2007, RWTH Aachen University has maintained a close partnership with the Tokyo Institute of Technology (TITech), Japan, through student exchanges and research cooperation. In 2021, the cooperation with TITech was continued with a joint event, which was an online event due to the current circumstances. RWTH Aachen University was again represented by Prof. Dr. Sven Ingebrandt. Prof. Dr. Masahiko Hara represented TITech.

The students from both universities had the opportunity to present their individual ideas from the field of micro- and nanotechnology on the topic. Mixed teams from Tokyo and Aachen were formed on the first workshop day on 01.07.2021, and their ideas were presented after one week on 08.07.2021.

The event also included presentations by Dr. Daisuke Ishikawa of TITech and Prof. Martin Trautz of the Faculty of Architecture at RWTH Aachen University. Science artist Heather Barnett from University of the Arts London acted as advisor.
