“…The data in the table demonstrate that the WUPs and IECs of the S 1 and S 2 membranes have higher values than those of the Nafion membrane, whereas the proton conductivities of the S 1 and S 2 membranes have lower values than those of the Nafion membrane. It has been reported that the high WUP and IEC values of the blend membrane (ionic membrane) might be due to the high concentration of SO 3 À1 availability in the blend membrane, which contains free charge carriers [18]. From the EDX analysis, it was proven that the S 1 and S 2 membranes have higher numbers of SO 3 À1 group.…”

“…The images show the formation of small and large pores in the PVDF/ PVP/PSSA blend membranes. The increased porosity and pore size led to an increase in the liquid electrolyte trapped within the pores, which increased the carrier ion content and enhanced the electrolyte conductivity accordingly [18].

“…5 (a) shows the EDX analysis of the PVDF, PVP, PSSA, S 1 , S 2 , and Nafion sample surfaces that were used to investigate the carbon (C), fluorine (F), oxygen (O), and sulfur (S) elements of the pure polymer and blend membranes. It has been reported that the EDX analyses of elements (C, F, O and S) of blend membranes could be related to the IEC and WUP of the blend membranes (ionic membrane) [18].…”

“…In practical application, the IPMC produces large actuation and large blocking forces. When a voltage is applied to an IPMC, the IPMC starts bending towards the anode direction due to the movement of the cations along with water molecules towards the cathode direction [18]. The blocking force of the IPMC depends on the actuation of the IPMC and stiffness of the IPMC membrane.…”

“…Third, the tip displacements of IPMCs using PVDF/ PVP/PSSA (60/15/25 and 40/30/30) blend membranes have been analyzed under AC voltages of 2e4 V at 0.1e5 Hz. Finally, the blocking forces of IPMCs have been analyzed as a function of time under DC voltages of 2 and 3 V. The different compositions used for making IPMC in the current study were compared with earlier studies [18,25]. The PVDF in the blend membranes is a hydrophobic polymer [25].…”

of responsive materials as machines is in robotics. The vision, leadership, and research of Bar-Cohen is seminal in both invigorating and focusing current-day research activities to develop responsive materials [2] and implement [3] them as lightweight, dexterous, and gentle (e.g., soft) robotic elements. In this spirit, this review exhaustively details the materials, the nature of their stimuli-response, and discusses considerations for their implementation in robotic systems and subsystems.Robotics is a well-established but growing field of research. Sustained progress in both performance and functionality continue to be realized in commercial robotic systems largely based on conventional materials and their integration with mechanisms. A recent example is the Atlas robot from Boston Dynamics [4] (Figure 1a). The incorporation of stimuli-responsive materials in robotics has largely focused on component-level demonstrations to extend the performance of a subsystem (such as a hand or gripper).Stimuli-responsive materials, spanning nearly all classes of materials and size scales, are currently subject to widespread examination in corporate, government, and academic research laboratories (Figure 1b-d). [5][6][7] In some cases, these materials have already found widespread commercial implementation in end use and are comparatively mature. The materials and fundamentals of their responses are summarized in Figure 2. Shape memory alloys (SMAs) and ceramic piezoelectric materials are distinctive in that they are hard, stimuli-responsive materials. Deformation of these materials can produce large energy densities due to their inherent stiffness. Electroactive polymers (EAPs) remain a topic of considerable interest, particularly dielectric elastomer actuators (DEAs). Engineered systems are rapidly emerging and enabling performance gains in robotics, largely based on pneumatic or fluidic (such as HASEL [8] actuators) transport processes that localize deformation to generate force or produce motion. Soft materials, such as shape memory polymers (SMPs), hydrogels, and liquid crystalline polymer networks (LCNs) and elastomers (LCEs) may offer distinctive functional performance to robotic systems in allowing local control of deformation without the need for complex interfacing with mechanisms. As will be evident, each of these materials has inherent advantages and performance tradeoffs that must be considered in functional implementations. However, responsive material systems have a common obstacle to widespread use: the performance and Machines are systems that harness input power to extend or advance function. Fundamentally, machines are based on the integration of materials with mechanisms to accomplish tasks-such as generating motion or lifting an object. An emerging research paradigm is the design, synthesis, and integration of responsive materials within or as machines. Herein, a particular focus is the integration of responsive materials to enable robotic (machine) functions such as gripping, lifting, or motility (walk...
