The startup "Magnexion" was founded in 2024 in Hamburg by 3 former scientists of Philips Research. The goal is to develop and market a wireless technology for localization of tiny objects. The first application is the diagnosis of gastro-intestinal disorders in the clinic or at the GP. For this, a detection system tracks ingestible magnetic particles inside the patient and provides their motion patterns for diagnosis. Compared to existing methods, no radioactivity or harmful X-ray is applied.
