1. ) A biomimetic tactile sensor for detecting a wide dynamic range of output signals comprising:

  • a) a substantially rigid core having 20-100 sensing electrodes distributed along the surface of the substantially rigid core, wherein each of the electrodes is configured to sense contact information relating to contact between the electrode and another object independent of the contact information sensed by the other electrodes;

    b) at least one deformable skin-like layer attached to the core; and

    c) detection circuitry mounted within the core and electrically coupled to the electrodes and configured to detect contact information sensed by each of the electrodes at a resolution of 12 or more bits per sample data, wherein each sample data is one contact information detected by each of the electrodes.
