Problems solved by technology

Traditional comb teeth are generally processed by MEMS, and the size ranges from millimeters to microns. It can be regarded as a planar structure, usually including a pair of comb structures, one fixed, and the other connected by a spring to ensure that the two comb structures do not touch. And it can move within a certain range, using alternating current plus direct current bias current to supply energy, the output frequency is high but the output force and power are low
