“…[ 1,10,11 ] Anisotropic hybrid systems of smart materials are critical for the development of actuators. [ 12–14 ] The methods that are currently available for the fabrication of anisotropic structures include one‐step method, [ 15,16 ] layer‐by‐layer polymerization, [ 17–19 ] 3D printing, [ 20 ] photolithography, [ 21 ] and ion printing. [ 22,23 ] These actuators contain crosslinking structures, and chemical crosslinking usually fixes the anisotropic structures of soft actuators and stabilizes their actuation performance.…”

Actuators have shown great promise in many fields including soft robotics. Since reconfiguration allows actuators to change their actuation mode, it is considered a key characteristic for new‐generation adaptive actuators. However, it remains a challenge to design simple and universal methods to fabricate actuators that can be reconfigured to allow diverse actuation modes. Here, a macroscopically discretionary healing‐assembly strategy to fabricate reconfigurable soft actuators based on intrinsic self‐healing poly(dimethylglyoxime‐urethane) (PDOU) elastomers is developed. The PDOU elastomers with different degrees of crosslinking show different responsiveness to solvents, and are seamlessly healed. Crosslinked and non‐crosslinked PDOU elastomers as building units are healing‐assembled into actuators/robots with diverse actuation behaviors. Notably, the assembled actuators/robots are readily reprogrammed to exhibit multiple actuation modes by simply tailoring and reassembling without any external stimuli. This work paves a new, simple, powerful, and universal method to construct sophisticated soft robots.

Toward Application of Liquid Crystalline Elastomer for Smart Robotics: State of the Art and Challenges

Liquid crystalline elastomers (LCEs) are lightly crosslinked polymers that combine liquid crystalline order and rubber elasticity. Owing to their unique anisotropic behavior and reversible shape responses to external stimulation (temperature, light, etc.), LCEs have emerged as preferred candidates for actuators, artificial muscles, sensors, smart robots, or other intelligent devices. Herein, we discuss the basic action, control mechanisms, phase transitions, and the structure–property correlation of LCEs; this review provides a comprehensive overview of LCEs for applications in actuators and other smart devices. Furthermore, the synthesis and processing of liquid crystal elastomer are briefly discussed, and the current challenges and future opportunities are prospected. With all recent progress pertaining to material design, sophisticated manipulation, and advanced applications presented, a vision for the application of LCEs in the next generation smart robots or automatic action systems is outlined.

“…These SMMs can be found in some everyday common devices and locations. In medicine, shape memory polymer (SMP) films are used as membranes for dosage forms [ 1 , 2 ], drug delivery systems [ 3 , 4 , 5 ], smart sutures and stents [ 6 ], in multiple cardiovascular applications [ 7 , 8 ], for antibacterial functions [ 9 ], and minimally invasive surgeries [ 10 ]. In aerospace [ 11 , 12 , 13 ], SMMs are used as active load-bearing elements in deployable panels [ 14 ], release devices during rocket launches [ 15 ], noise-reducing jet nozzles [ 16 ], aerodynamic load suppression systems [ 16 , 17 ], bilinear controllers [ 18 ], phase-changing light-responsive components [ 19 ], and various actuators [ 20 , 21 , 22 ].…”

Recording, Storage, and Reproduction of Information on Polyvinyl Chloride Films Using Shape Memory Effects

Partial dissolution and plasticization are used for recording, storing, and reproducing information with modified industrial screen-printing equipment and aqueous solutions of colorless organic liquids on small surface area shape memory polymer films. To justify the choice of “ink” and evaluate the effectiveness of using organic liquids as high-speed polymer solvents, the new method for recording hidden information uses the calculation of the solubility parameter, differential scanning calorimetry, and the method of one-sided swelling of films under isometric conditions. Using the example of tactile marking of shrink labels made of polyvinyl chloride, the optimal conditions for recording hidden information on a film are established in terms of the concentration of an aqueous solution of tetrahydrofuran, the contact time, and the processing temperature of the polymer using screen printing equipment.
