Soft robots driven by stimuli-responsive materials have unique advantages over conventional rigid robots, especially in their high adaptability for field exploration and seamless interaction with humans. The grand challenge lies achieving self-powered soft mobility, environmental tolerance, long endurance. We are able to advance a electronic fish fully integrated onboard system power remote control. Without any motor, the is solely electroactive structure made of dielectric elastomer...
Abstract An effective approach to develop a novel macroscopic anisotropic bilayer hydrogel actuator with on–off switchable fluorescent color‐changing function is reported. Through combining collapsed thermoresponsive graphene oxide‐poly( N ‐isopropylacrylamide) (GO‐PNIPAM) layer pH‐responsive perylene bisimide‐functionalized hyperbranched polyethylenimine (PBI‐HPEI) via supramolecular assembly, obtained that can be tailored and reswells form 3D actuator.

Inspired by the assembly of Lego toys, hydrogel building blocks with heterogeneous responsiveness are assembled utilizing macroscopic supramolecular recognition as adhesion force. The provides 3D transformation upon pH variation. After disassembly changing oxidation state, they can be re-assembled into a completely new shape. As service to our authors and readers, this journal supporting information supplied authors. Such materials peer reviewed may re-organized for online delivery, but not...
For a hydrogel coating on substrate to be stable, covalent bonds polymerize monomer units into polymer chains, crosslink the chains network, and interlink network substrate. The three processes-polymerization, crosslinking, interlinking-usually concur. This concurrency hinders widespread applications of coatings. Here principle is described create paints that decouple polymerization from crosslinking interlinking. Like common paint, paint divides labor between maker user. formulates by...
Hydrogels consist of cross-linked polymers that are highly swollen with water. Water evaporation or freezing during temperature changes may lead to stiff and brittle hydrogels. We introduce a strategy called “hydro-locking,” which involves immobilizing the water molecules within polymer network hydrogel. This is accomplished by establishing robust connections between using sulfuric acid. A sacrificial introduced shield prime from collapsing. Under hydro-locking mode, an...

The runs four times its body length per second turns at radius about three 0.3 s. survives compression...
Typical hydrogels undergo slow and continuous shape change. Inspired by the Venus Flytrap, current work presents a hydrogel assembly that can reversibly non-continuous rapid snapping change due to bi-stable structure of assembly. In particular, reversible goes beyond Flytrap is not known in literature.
Inspired by nature, diverse biomimetic hydrogel actuators are fabricated and become one of the most essential components bionics research. Usually, anisotropic structure a actuator is generated at early fabrication process, only specific shape transformation behavior can be produced under external stimuli, thus has limited development toward deformation behavior.

With the ability to deform in response specific stimuli, polymeric hydrogel actuators are important bionic materials. However, because shape deformation is derived from diffusion of water molecules, rate usually slow, which severely limits their potential applications.

Manipulating charges is fundamental to numerous systems, and this ability achieved through materials of diverse characteristics. Electrets are dielectrics that trap or dipoles. Applications include electrophotography, microphones, air filters, energy harvesters. To dipoles for a long time, electrets commonly made hard dielectrics. Stretchable short–lived electrets. The two properties, longevity stretchability, conflict; existing struggle attain both. This work describes an approach...
Bilayer hydrogels are attracting tremendous attention for their capability to integrate several different functions on the two sides of gel, that is, imparting gel with Janus characteristics, which is highly desired in many engineering and biomedical applications including soft actuators, hydrogel patches, wearable electronics. However, preparation process bilayer materials usually involves complicated steps time-consuming, while interfacial bonding another main concern. Here, a simple...
Natural locomotion such as walking, crawling, and swimming relies on spatially controlled deformation of soft tissues, which could allow efficient interaction with the external environment. As one ideal candidates for biomimetic materials, hydrogels can exhibit versatile bionic morphings.

Dielectric elastomers (DEs) can demonstrate fast and large in-plane expansion/contraction due to electric field (e-field)-induced Maxwell stress. For robotic applications, it is often necessary that the actuation converted into out-of-plane motions with mechanical frames. Despite their performance appeal, high driving e-field (20-100 V µm-1 ) demands bulky power accessories severely compromises durability. Here, a dielectric polymer be programmed diverse actuated under low (2-10 reported....
