Sliding non-contact inductive nanogenerator

Abstract Nanogenerators generate power by inducing charge moving between the electrodes after charge generation. Using this principle, all the generated charges have the potential to design nanogenerators. In this work, we designed a new configuration that can generate power by electrostatic induction in a universally applicable way. The conversion efficiency of the contact and non-contact configuration was compared and it was found that the output capability of the non-contact inductive nanogenerator (NCING) did not decrease significantly. In addition to the traditional triboelectric non-contact mode and electret induced power generation, it was found that this configuration is applicable to more charge-induced power generation, so we directly used a charged capacitor to complete the induction power generation, which has not been reported yet. Through these experiments, we have proven the powerful ability of the free sliding non-contact configuration. In future research, the charge source can be replaced with other ones. By controlling the fixed charge to generate a higher potential, the output can be improved. Therefore, this wide-applicable generation mechanism has a huge impetus to the design of new nanogenerators.
