Tactile sensor is an essential component for realizing biomimetic robots, while the flexibility of the tactile sensor is a

pivotal performance for its application, especially for electronic skin. In this work, a flexible self-powered tactile sensor

array was designed based on the piezoelectricity of ZnO nanorods (NRs). The field-limited ordered ZnO NRs were

synthesized on flexible Kapton substrate to serve as the function layer of tactile sensor. The electrical output

performances of as-fabricated tactile sensor were measured under pressing and bending forces. Moreover, we measured

the human-finger pressure detection performance of tactile sensor array, suggesting that the corresponding mapping

figure of finger pressure could be displayed on the monitor of personal computer (PC) in the forms of lighted LED and color

density through LabVIEW system. This as-grown sensory feedback system should be a potential valuable assistance for the

users of hand prostheses to reduce the risk and obtain a greater feeling of using of the prostheses.
