influencing the optimized miniaturization of associated power sources. Microcompressors powered by
batteries are a popular choice owing to various available options, each tailored to the energy and control
requirements of the specific system [60,67,68] . They work well for low-pressure systems; if larger pressures are
required, a reconfiguration of multiple micro-compressors can be used, introducing more mass and volume
to the total of the system. Another promising power source for pneumatic actuation is using soft electro-
pneumatic pumps (EPPs) proposed by Diteesawat et al. . Using the dielectrophoretic liquid zipping (DLZ)

principle, a small bead of dielectric liquid between the closest point(s) of two electrodes amplifies the
