Electronic skins endow robots with sensory functions but often lack the multifunctionality of natural skin, such as switchable adhesion. Current smart adhesives based on elastomers have limited adhesion tunability, which hinders their effective use for both carrying heavy loads and performing dexterous manipulations. Here, we report a versatile, one-size-fits-all robotic adhesive skin using shape memory polymers tunable rubber-to-glass phase transitions. The strength our can be changed from...
Abstract Bistable morphing structures are widely used as actuation mechanisms in soft actuators, robotics, energy absorbers, mechanical computers, optical lenses, metamaterials, and flexible electronics. However, untethered repetitive hybrid‐assembly (containing in‐plane‐assembly out‐of‐plane‐assembly) actuators remain challenging to realize using existing bistable structures, which hinders the novel application of such research, engineering, daily life. This problem is solved by fabricating...
Abstract Ultraflexible neural probe is an ideal tool for brain research, which can reduce the mechanical interfacial mismatch between electrodes and tissue thus tissue's inflammation extend electrodes' service life. However, low stiffness of ultraflexible makes it susceptible to bending buckling during insertion into brain. Here, a simple yet robust design removable shuttle consisting steel needle with dissolvable spheroid micropost reported implantation. The fabricated by dip‐coating...
Abstract Transfer printing based on switchable adhesive that heterogeneously integrates materials is essential to develop novel electronic systems, such as flexible electronics and micro LED displays. Here, we report a robust design of thermal actuated dry adhesive, which features stiff sphere embedded in thermally responsive shape memory polymer (SMP) substrate encapsulated by an elastomeric membrane. This construct bypasses the unfavorable micro- nano-fabrication processes yields adhesion...
Surface wrinkling of an elastic graded layer is studied theoretically, numerically and experimentally.
The buckling of a stiff film on compliant substrate has attracted much attention due to its wide applications such as thin-film metrology, surface patterning and stretchable electronics. An analytical model is established for the thin semi-infinite elastic graded subjected in-plane compression. critical compressive strain wavelength sinusoidal mode are obtained analytically case with modulus decaying exponentially. rigorous finite element analysis (FEA) performed validate investigate...
Exiting strategies for 3D shape-changing structures are constrained by either the complicated fabrication process or harsh demands of active materials. Facile preparation with an extremely simple approach based on elastomeric polymer still remains a challenging topic. Here, we report fast digital patterning surface topography single-layer toward structures. The features digitally engraved grooves laser engraver poly(dimethylsiloxane) (PDMS) sheet, which is oxidized UV-ozone treatment....
Mechanical robustness is one of the key factors for future commercialization wearable electronics. Wearable electronics are thin constructed on flexible polymer or rubber substrates. Due to their geometry, typically vulnerable under tearing stretching, especially when cracks exist. This paper presents designs and manufacturing crack-insensitive realized through incorporating high-strength Kevlar fabrics. Manufacturing strategies transfer printing prefabricated onto fabric with adhesion layer...
In the petroleum engineering and chemical industries, fluids engaging in displacement often have non-Newtonian properties, even though many former studies assume constant viscosities defending fluid. this study, computational fluid dynamics approach was performed a two-dimensional model with uniformly distributed disks. This arrangement helps reveal phenomenon mechanics of how characteristics affect two-phase porous media. Both global (in whole medium) regional pore throat) revealed that...
