AI Technical Summary

Technical Problem

The output power and power generation efficiency of existing liquid-solid friction nanogenerators are low, and cannot meet the power supply needs of high-power equipment.

Method used

A square liquid-solid friction nanogenerator is designed, using an external support structure, induction electrode, polymer material and friction liquid. Charge transfer is generated through the reciprocating flow of the friction liquid in the support structure and friction with the polymer material, and induces induction charge on the induction electrode to output alternating current.

Benefits of technology

The output power and power generation efficiency of the generator are improved, so that it can adapt to a wider range of application scenarios, and the space utilization efficiency is improved by integrating multiple generators to achieve omnidirectional and homogeneous energy capture.
