Electronic Receptors for Tactile/Haptic Sensing

ABSTRACT We discuss synthetic receptors for haptic sensing. These are based on magnetic field sensors (Hall effect structures) fabricated using standard CMOS technologies. These receptors, biased with a small permanent magnet can detect the presence of ferro or ferri-magnetic objects in the vicinity of the sensor. They can also detect the magnitude and direction of the magnetic field. INTRODUCTION The organizational structure and functioning of the sensory periphery in living beings has always been the subject of extensive research.
