Abstract

Additive manufactured micro-optical systems and elements via two-photon polymerization already show a wide range of applications. To extend that range, mechanical features such as autofocus, zoom or tilting could be realized by implementing actuatable components in the printed opto-mechanical design. We demonstrate a magnetic actuation principle, where ferromagnetic fluids are injected into predefined microcavities. In this way, optical parts can be actuated through external magnetic fields in continuous manner and restored to their original position by retracting mechanical components embedded in the design. We demonstrate different kinds of motions regarding use cases in endoscopic applications.
