Abstract
An axial force sensor, a robot gripper and a robot are provided. The axial force sensor includes a sensing diaphragm and at least two signal pairs. The sensing diaphragm includes an inner ring, an outer ring and a connecting element connected between the inner ring and the outer ring. The connecting element is more compliant in a direction of the axial force to be detected than in other loading directions. Each signal pair includes a signal emitter and a signal receiver. The signal emitter is coupled to one of the inner ring and the outer ring. The signal receiver is coupled to the other of the inner ring and the outer ring.
