Abstract
Abstract As we known, nanogenerator (NG) can be used in many fields, such as sensors, energy harvesting, biomedical application, and so on. Sometimes, the object that is a part of NG cannot be electrically connected to the load because it is a mobile object. To harvest energy from such a case and reduce the fabrication cost and achieve some new applications such as touch screen products, we need to find new method to fabricate NG. To attain the higher output current and output power, moreover, here we report a flexible and easy fabricated single electrode triboelectric nanogenerator (TENG) based on polydimethylsiloxane (PDMS) and silver (Ag) nanowires (NWs). Due to Ag NWs high specific surface area, the electrical conductivity of Ag NWs is better than the block of Ag, and PDMS is the transparent and flexible. The single electrode TENG not only can harvest energy from environment but also is a self-powered sensor for detecting acceleration from different angles. This TENG can attain an open-circuit voltage up to 330 V, a maximum short-circuit current of 15.5 μ A (2.6 μ A/cm2) and a maximum power of 1.5 mW (0.25 mW/cm2) on the load of 20 MΩ.
