IntroductionIn order to enhance the sensitivity of PVDF-based tactile sensor, we introduced the so-called structural electrode to replace the thin-film electrode in the traditional design.We developed the shape recognition also can be achieved as the objective contacted with the 4 by 4 electrodes array.In addition, a novel flexible tactile sensor for sensing the force direction were designed by introducing the concept of structural electrodes on a piezoelectric film (PVDF).

Multi-axial Tactile Sensor for recognize direction
This research has proved that utilizes the phase place of the structural electrode with distinguishing the force's direction.
Numerical analysis with structure electrodes
In order to investigate the influences on introducing microstructures, a 3D model was established and analyzed by finite element software (ABAQUS) .
