Background: In order to implement the principle of rehabilitation before care, adaptive concepts for geriatric patients are required. Patients with visual impairments, impaired communication skills, mental illnesses or cognitive deficits are often not or only insufficiently treatable in a rehabilitation clinic. Mobile geriatric rehabilitation (MoGeRe) closes this gap in the care system, but its scope is limited.

- Noble metal oxide additives significantly alter the sensing characteristics of metal oxide sensors, particularly through a mechanism called Fermi level pinning, as observed with platinum-loaded WO using operando infrared spectroscopy.
- Traditional methods like microscopy provide structural insights but don't reflect real operational conditions since they're often done in a vacuum and on unheated samples.
- The use of advanced in situ scanning transmission electron microscopy allows for detailed observations of heated samples in various gas environments, linking structural changes in noble metal nanoclusters to their infrared spectra and sensing responses, ultimately validating the Fermi level pinning mechanism.
