Abstract: The present invention relates to an Ocular Videography System for tracking eye movements of an animal, in particular rats, comprising a camera system suitable of being positioned on the head of an animal to track eye movements of at least one eye of the animal, a head mount on which the camera system is fixed or fixable, wherein, at least one image sensor as well as at least one decoder, for decoding a signal detected by the image sensor, each being comprised by the camera system, and wherein the camera system, and in particular a camera of the camera system, is designed in such a way that it detects a movement of the eye and/or a movement of the head of the animal in a vertical and/or horizontal and/or a torsional direction to an optical axis of the camera system and/or of the optical axis of the animal's eye without interfering with the animal's natural motion dynamics.

Abstract: A sensor device having a magnetostrictive force sensor is provided. To detect a force, the sensor device contains a TMR force sensor element having a magnetic detection layer of material having a magnetostriction coefficient ??|5·10?6|, a magnetically harder reference layer, and a tunnel barrier disposed between these layers. Established in the detection layer is a starting magnetization that relative to the magnetization of the reference layer, which is directed in the direction of force, forms an angle of other than 0° and thus is rotated out of its starting position under the effect of the force.
