“…Inchworm actuators have high thrust and high resolution [ 26 , 27 , 28 ], and utilizing the inchworm principle increases the stroke by accumulating paces of the actuator and can obtain very high resolution within one pace [ 29 , 30 ]. In the existing research on inchworm actuators [ 31 , 32 ], the way to realize clamping and release mainly depends on the deformation of laminated piezoelectric ceramics or the deformation of mechanical amplification mechanism actuated by laminated piezoelectric ceramics.…”

“…Actuators for shape adjustment can be very needed for mesh antennas. Considering the requirements of shape adjustment, several different types of actuators have been proposed, such as piezoelectric ceramic (PZT) actuators, shape memory alloys, ultrasonic motors and inchworm actuators (Torisaka et al , 2019; Dong et al , 2020). Among them, the inchworm actuator is a preferable technical solution for shape adjustment.…”

“…1a according to previous studies [21]. However, the inchworm actuator usually needs two sets of clamping units, one set of driving unit and a multi-channel control system, which leads to the problems of complex structure and control system [22]. This limits the practical application of inchworm actuators seriously.…”
