ELECTRONIC SKIN BASED ON DIRECT CURRENT TRIBOELECTRIC NANOGENERATOR

Abstract

The present work discusses the control of the slip and sliding of the objects on the surface of the electronic skin (e-skin).The slip or sliding of the object on the e-skin generates ESC that works as feedback signal generated by using the electrostatic breakdown effect to generate a direct current TENG (DC-TENG) to control the gripping force by controlling the input voltage of the control system of the grasping force between the e-skin and object.In the present work, a design of e-skin of feedback action depending on triboelectrification and electrostatic breakdown of proposed DC-TENG is proposed.During sliding of the object on the surface of the eskin, DC-TENG generates DC current that works as feedback signal to control the gripping force.It was found that the proposed design of the e-skin that includes latex as the outer layer can guarantee safe grasping of the objects, where results of experiments proved that latex has relatively high friction coefficient.It was observed that the highest voltage values were measured for PTFE and Kapton as friction surface (FC).When two charge collecting electrodes (CCE) at rear and front of the FE were used, the voltage in the external circuit remarkably increased.It is recommended to apply the DC-TENG in the design of e-skin.Finally, further research should be continued to optimize the factors that control the performance of DC-TENG.
