Abstract
A piezoelectric tactile sensor comprises a piezoelectric membrane with a top surface, a transducer of elastic column with a bottom end surface to overlay over the top surface of the piezoelectric membrane and plural microelectrodes being sandwiched between the top surface of the piezoelectric membrane and the bottom end surface of the transducer in spread manner. When the transducer is subjected to an external stress, the piezoelectric membrane will generate uneven stress distribution to initiate dispersed microelectrodes output a corresponding induced voltage signal for being analyzed to figure out the direction and magnitude of the external stress.
