Versions Notes

The editorial team of the journal Micromachines would like to make the following changes to the published paper [1]: The captions of Figure 2 and Figure 3 are correct, however, the images of Figure 2 and Figure 3 should be exchanged as follows:

We apologize for any inconvenience caused to the readers or authors by this error. The change does not affect the scientific results. The article will be updated and the original will remain on the article webpage.
