The program in the iL conference room was concluded with two lightning talks by Dr. Johannes Zimmermann (InnovationLab) and Professor Gerardo Hernandez-Sosa from the Karlsruhe Institute of Technology (KIT). Zimmermann, a former doctoral student of Hernandez-Sosa, focused his keynote presentation on the topic “PreMoo – Small Patients, Great Need.” This three-year project, supported by the Federal Ministry of Education and Research (BMBF) since June 2021, addresses the early detection of electrolyte imbalances in premature infants. The young patients are monitored using a non-invasive methodology and continuous surveillance. The objective is to develop an integrated, wearable sensor solution for detecting electrolyte levels in the sweat of premature infants. The role of iL GmbH in this endeavor is the process development for the commercial production of printed electrolyte sensors.
Gerardo Hernandez-Sosa, who has been researching printed electronics at iL for KIT for over ten years, presented on “Inkjet-Printed Thin-Film Sensors for Wearables.” Through experiments with inkjet printers, solar, and weather simulators, reference values for light or humidity sensors can be established. The sensors utilized are flexible and deformable, essentially a mere whisper, described as “a small island with a rigid substrate in a stretchable environment.” This piqued the participants’ curiosity, and discussions about potential collaborations quickly ensued. “I am 100 percent ready for it,” Hernandez-Sosa stated with a grin. Both presentations were followed by a concluding tour of the adjacent iL cleanroom in Hall L.
