Zusammenfassung Akkommodation, die Fähigkeit von der Nähe bis in die Ferne scharf zu sehen, ist mit ca. 50 Jahren so stark eingeschränkt, so dass wir eine Sehhilfe, z. B. eine Brille, verwenden müssen. Ein neuer Ansatz zwischen unendlich und Lesedistanz eine stufenlose Akkommodation wiederherzustellen, ist die Implantation eines optischen Mikrosystems anstelle einer Intraokularlinse. Es werden Konzept und Realisierung des Systems als Funktionsmodell im Maßstab 2:1 beschrieben.

Abstract For package testing of active implants internal humidity measurements are performed. Thereby, the water absorbency of the measurement components can affect the measurement result, leading to an erroneously prolonged predicted lifetime. Here, the influence of internal components is discussed using an exemplary setup. It is described how to model and consider the components’ absorbencies for lifetime estimation and how beneficial they are during implant operation.

Abstract An automated accelerated aging test procedure is presented to estimate the lifetime of implant packages regarding hermeticity. Intruding humidity is captured automatically in packages at two elevated temperatures using a resonant circuit comprised of capacitive humidity sensor and coil in coupling with an external coil. Described are the test stand setup including sensor calibration and evaluation, data acquisition and processing. In a first application the safe and reliable operation of the setup is demonstrated.
