摘要： A patterned magnetic recording media and method thereof is provided. A recording layer comprises a continuous surface of more-noble elements and less-noble elements, such as CoXYZ, wherein X can be Pt, Pd, Ru, Rh, Ir, Os, or Au, wherein Y can be null or Cr, and wherein Z can be null, Cu, Ta, Ti, O, B, Ag, or TiO2. The recording layer is masked, shielding areas for recording domains and exposing areas between the recording domains. A voltage bias establishes the substrate as an anode in the presence of Pt cathode, in an electrolyte bath. Ions of the less-noble element are anodically removed predominantly from the exposed areas of the recording layer for a controlled time. The controlled time minimizes oxidation of the nobler element and reduces undercutting of the recording domains. The article produced can have separating areas with surfaces substantially formed of the more-noble element.

摘要： 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.

摘要： A trilayer magnetoresistive sensor has at least first and second ferromagnetic layers separated by a nonmagnetic layer. A high coercivity permanent magnet bias element biases the first ferromagnetic layer in a first direction.
