Problems solved by technology

Another example is in the field of superhydrophobic, which is also affected by the limitations and performance of superhydrophobic materials, and there is a decline in electrical output performance when applied in a humid environment.
In addition, relevant reports have confirmed that increasing the surface roughness and applied charge of the friction layer material can also improve its electrical output performance. However, the methods of photolithography and high-voltage polarization in traditional reports are not only costly, but also complicated to operate. , and there is a certain risk
