Abstract: Methods, systems, and programing of one tactile sensor are presented. In one example, magnetic sensors containing one or more layers are formed on a base substrate for sensing a magnetic field generated by one ferromagnet present in close proximity to the magnetic sensors. The ferromagnet is embedded in an elastomer matrix. When an external force is applied to the elastomer matrix, it deforms and displaces the ferromagnet. As a result, the magnetic field generated by the ferromagnet changes. This change is sensed by the magnetic sensors to in turn quantify the applied force.
