Force-moment Sensor

The invention relates to a force-moment sensor for measuring at least one force and/or a moment. Said force-moment sensor comprises a first part (1), a second part (2), and an intermediate optical fiber (3), at least one section of which is provided with a means (5) for sensing deformations and/or strains of the fiber (3) transverse to the longitudinal axis thereof. The invention further relates to a method for measuring forces and/or moments. In said method, a fiber (3) is provided that comprises at least one means (5) for sensing deformations and/or strains of the fiber (3) transverse to a longitudinal direction of the fiber (3) into which light is introduced. According to the method, a force and/or a moment then acts on the fiber (3), at least one component of the force and/or the moment acting perpendicular to the longitudinal axis of the fiber (3). The light reflected in the fiber (3) is then detected, and the detected spectrum is analyzed.
