Triboelectric effect is an usual case of daily life’s electrostatic behavior through contact friction, leading to development of wearable triboelectric devices. We design a multilayer triboelectric nanogenerator with tunable tactile sensitivity consisting of self-healable polymers and Ag NW composite gel. The triboelectric current and voltage increase 5 times more than those without the composite gel, which is attributed to the increase of capacitance and ionic effect through the composite gel. The coated Ag NW between the polymer layers shows a constant directional arrangement, resulting in different sensitivity during rolling with different direction and touching at different position on the material surface without nanogenertator arrays. We demonstrate simple assembly of triboelectric device by self-healing of the polymer, leading to formation of multilayer nanogenerator. Our approach will provide a chance to design an electronic skin with controlled sensitivity and self-healing. |
