Problems solved by technology

Although the vertical generator has achieved great success and derived models based on different substrates, its further development still faces some difficulties that need to be resolved urgently

One challenge comes from the precise control of the distance between the driving electrodes and the ZnO nanowires, a small amount of error can cause the generator not to work properly

In addition, when the vertical generator is working, the free end and the driving electrode are in constant contact and friction, which may cause wear of the nanowires and electrodes, thereby affecting the performance and life of the nanogenerator

Recently, the use of packaged horizontal single zinc oxide nanowires not only realizes the conversion of mechanical energy to electrical energy, but also solves the problem of wear and tear of nanogenerators; Operating requirements for most passive nanodevices
