Abstract: A print head includes a capillary around an axis of symmetry for a liquid to be printed, the capillary adjoining at least one elastic element and having a nozzle opening which opens into a prechamber. The prechamber has an outlet opening aligned with the nozzle opening of the capillary in its axial orientation of the axis of symmetry and at least one inlet opening for a guide gas. The at least one elastic element forms a guide for the capillary in its axial orientation only. A feed for the liquid to be printed is provided in the capillary. A mechanical oscillation system is provided that includes the at least one elastic element and the capillary with the liquid contained therein. An actuator with a mechanical or magnetic force interaction with the oscillation system is further provided.

Abstract: A wide-angle optical unit for ophthalmological implants in the eye includes a lens system arranged in a rotationally symmetrical manner about an optical axis and further includes at least two lenses that rest one on top of the other in a planar manner and which are made of materials having different optical refractive indices. In addition, the wide-angle optical unit includes an optical decoupling structure and a trailing lens arranged proximally with respect to the interior of the eye. The trailing lens is mounted around the optical decoupling structure.

Abstract: In a sensor system for determining the control signal supplied to the ciliary muscles of an eye for adjusting the focal length of the lens of an eye, a contact element of an electrically non-conductive material and provided with sensors is disposed on the cornea of the eye so that the sensors are arranged in contact with an annular area of the cornea next to the ciliary eye muscles so as to be able to sense the focal adjustment signals supplied to the ciliary muscles and the sensed adjustment signals are supplied to a signal processing unit which provides a control signal to a lens system with adjustable focal length for adjusting the focal length thereof depending on the focal adjustment signals of the ciliary eye muscles.
