“…Figure 4 depicts the evolution of the PneuNet structure, which can be classified into three aspects: 1) stiffness improvement through chamber gaps, [35] chamber length, [92] material selection, [90] spatial channel design, [15] and/or the incorporation of rigid component [20,93] ; 2) dexterity improvement through multi-activation unit [22,25,90] and/or segment designs [28] ; and 3) contact area improvement through assembling a flat soft surface. [94,95] Specifically, eliminating chamber gaps preferentially expands the inside walls and minimizes strain that occurs on the other exterior walls, thereby increasing motion speed and robustness.…”

“…Drawing inspiration from natural creatures such as earthworms, [10] octopuses, [11] jellyfish, [12] elephant trunks, [13] and twining plants, [14] researchers have designed soft robotic actuators capable of fulfilling the grasping requirements for agricultural applications. For instance, multiple actuators can be combined into a gripper, as single soft actuators can lift weights successfully but may struggle to grasp objects [15] unless they possess the ability to twist and hold objects like a tentacle. [13,14] In contrast, envelope actuators [16][17][18] offer the advantage of a large contact area by enclosing objects within their body, eliminating the need for complex energy input strategies.…”

The use of high electric fields, as well as pre‐stressing, are the two main obstacles to the widespread use of poly(vinylidene fluoride (PVDF)‐based actuators. In response, a new double‐sided multilayer device has been developed which, coupled with a polarization procedure, enables high bending performance at low voltages. The actuator's symmetry allows zero bending at rest, while the high number of layers enables a strong field to be maintained while reducing the applied voltage. X‐ray and permittivity studies reveal the ultimate links between the microscopic material displacement and the actuator deflection. These results, coupled with the analytical model developed in this work, demonstrate that the optimization of complex multilayer systems requires a detailed understanding of mechanics, design, and microstructure. Experimental, analytical and finite element results confirm that such a double‐sided multilayer actuator is of 50% more efficient than a conventional single‐sided actuator, up to 40 V µm−1. These achievements open up new prospects for PVDF‐based actuators in application of healthcare, such as arterial navigation.
