ABSTRACT:
In a tactile opto-electronic pressure sensor having a body with a rigid matrix including axially extending bores in which hollow cylinders of an elastic material are firmly disposed such that the front ends of the hollow cylinder project from one side of the matrix while the opposite ends of the hollow cylinders are flush with the other side of the matrix, a light emitting electro-luminescent foil is disposed on the front faces of the hollow cylinders such that light emitted therefrom shines through the hollow cylinders and is recorded by an evaluation device arranged at the other side of said matrix, the hollow cylinders being axially compressible such that their openings become smaller with increasing forces acting thereon, the light intensity received by the evaluation units depending on the forces applied to the hollow cylinders.
