Simulation of the microswimmer rotates above a no-slip wall. Rotation axis is defined as Z-axis; numbers represent dimensions in micrometer. The microswimmer with two different boundary conditions is modeled a \(0.75 \,\upmu \hbox {m}\) and d \(20.75 \,\upmu \hbox {m}\) above the no-slip wall, as shown in the insets of a and d, respectively. a, b The streamlines generated by the microswimmer. b, c, e, f Pressure induced by rotation of the microswimmer at a frequency of 10 Hz in a plane \(0.5 \,\upmu \hbox {m}\) below b, e and above c, f the microswimmer, b, c are with the microswimmer \(0.75 \,\upmu \hbox {m}\) above the no-slip wall, and e, f are \(20.75 \,\upmu \hbox {m}\) above the no-slip wall. The color legends in the main frame illustrate the magnitude of pressure (Pa). The red areas of insets in b, e are with pressure higher than 0.1 Pa, and those in e, f are higher than 0.04 Pa. b, c, e, f with all insets have the same coordinate
