The invention discloses a tactile sensor, comprising: a cantilever platform, a cantilever is fixedly connected to the cantilever platform, the cantilever includes an inner cantilever and an outer cantilever, the inner cantilever has conductivity, and the inner cantilever is provided with multiple a crack, the inner cantilever is electrically connected to the stress signal receiving device arranged on the cantilever platform; the inner cantilever is fixedly connected to the outer cantilever, and the elastic modulus of the inner cantilever is smaller than the elasticity of the outer cantilever Modulus, the end of the outer cantilever away from the inner cantilever is provided with a contact layer. Due to the high modulus of elasticity of the outer cantilever, it deflects when subjected to stress, and the slight stress change can also be concentrated and completely transmitted to the inner cantilever, and the multiple cracks in the inner cantilever make the inner cantilever can be easily deformed when it is slightly deformed. A larger resistance change is generated, which improves the perception sensitivity of the tactile sensor.
Description
technical field [0001] The invention relates to the field of tactile sensing, in particular to a tactile sensor. Background technique [0002] With the rapid development of intelligent machines, tactile sensing has become an important research direction of intelligent machines. The precise detection of object surface texture is the goal that machine tactile perception has been striving for. However, in the existing technology, the sensitivity of tactile sensors Generally low, especially for the perception of fine textures on the surface of objects. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a tactile sensor aiming at solving the problem of low sensitivity of the tactile sensor in the prior art, aiming at the above-mentioned defects of the prior art. [0005] In order to solve the problems of the technologies described above, the tec...
