The integration of lignocellulosic nanomaterials into energy management applications possesses enormous technical appeals catering to high-tech and low-carbon era. Nature has designed hierarchical and heterogeneous lignocellulose microstructure, which can be harnessed for desirable dielectric behaviors towards specific applications. Here, we make the first attempt to boost the tribopositivity of 2D self-assembly (i.e., nanopaper) of cellulose nanofibrils by leveraging the inherent functionality of their hemicellulose phase. In comparison to conventional nanopapers assembled from TEMPO-oxidized/enzymatic cellulose nanofibrils with significantly lower hemicellulose content (4.6/12.2 vs. 20.3 wt%), the as-prepared hemicellulose-rich nanopaper exhibits ~2-fold higher electron-donating capability, which in turn generates ~1.5-fold higher triboelectric nanogenerator (TENG) output when paired with given tribonegative materials. We provide multiscale insights into the boosted tribopositivity of nanopaper by hemicellulose phase arising from its unique molecular structure and micro-distribution pattern. Furthermore, amorphous hemicellulose phase can be readily molecularly designed, e.g., aminosilanization, which further enhances the tribopositivity of nanopaper towards self-powered applications requiring high energy density. Besides, the hemicellulose-rich nanopaper is highly writable, mechanically strong, and optically transparent, serving as a desired structural material with favorable programmability for various TENG-based sensing, encryption and wearable devices.

Vitrimers with covalent adaptable networks usually show low mechanical properties and water resistivity. Here, we report an epoxy vitrimer which possesses not only high weldability, malleability and programmability, but also outstanding mechanical properties and water insensitivity. Such epoxy vitrimer is fabricated by crosslinking diglycidyl ether of bisphenol F (DGEBF) with a novel curing agent bearing imine backbones and amino terminals. The curing agent is synthesized by a one-pot reaction between 3-aminobenzylamine and terephthalaldehyde by taking advantage of the different reactivity of the aromatic amine and aliphatic amine. The dynamic imine bonds of the curing agent enable malleability, shape reconfiguration and programming of the epoxy vitrimer, while the aromatic structure of the curing agent imparts the epoxy vitrimer with high tensile strength, Young modulus and thermal stability. Moreover, the epoxy vitrimer is highly water-resistant due to the hydrophobicity and high crosslinking density of the network. Such a combination of comprehensive properties and convenient fabrication approach makes the epoxy vitrimer hold great promise to serve as structural materials in diverse applications.

Natural polymer substrates are gaining attention as substitutes for plastic substrates in electronics, aiming to combine high performance, intricate shape deformation, and environmental sustainability. Herein, natural wood veneer is converted into a transparent wood film (TWF) substrate. The combination of 3D printing and origami technique is established to create programmable wood-based origami electronics, which exhibit superior flexibility with high tensile strength (393 MPa) due to the highly aligned cellulose fibers and the formation of numerous intermolecular hydrogen bonds between them. Moreover, the flexible TWF electronics exhibit editable multiplexed configurations and maintain stable conductivity. This is attributed to the strong adhesion between the cellulose-based ink and TWF substrate by non-covalent bonds. Benefiting from its anisotropic structure, the programmability of TWF electronics is achieved through sequentially folding into predesigned shapes. This design not only promotes environmental sustainability but also introduces its customizable shapes with potential applications in sensors, microfluidics, and wearable electronics.

Currently, it remains challenging to balance intrinsic stiffness with programmability in most vitrimers. Simultaneously, coordinating materials with gel-like iontronic properties for intrinsic ion transmission while maintaining vitrimer programmable features remains underexplored. Here, we introduce a phase-engineering strategy to fabricate bicontinuous vitrimer heterogel (VHG) materials. Such VHGs exhibited high mechanical strength, with an elastic modulus of up to 116 MPa, a high strain performance exceeding 1000%, and a switchable stiffness ratio surpassing 5 × 103. Moreover, highly programmable reprocessing and shape memory morphing were realized owing to the ion liquid–enhanced VHG network reconfiguration. Derived from the ion transmission pathway in the ILgel, which responded to the wide-span switchable mechanics, the VHG iontronics had a unique bidirectional stiffness-gated piezoresistivity, coordinating both positive and negative piezoresistive properties. Our findings indicate that the VHG system can act as a foundational material in various promising applications, including smart sensors, soft machines, and bioelectronics.

While liquid crystal elastomers (LCEs) show promise for diverse soft actuators due to their strong stimulus responsiveness, limited investigation into their light perception and processing restricts their wider use in intelligent systems. This study employs a hollow double-layer structure to design light-controlled logic soft switches based on LCEs. The design realizes digital logic circuits including AND gates, OR gates, and NOT gates, as well as an optical switch array capable of converting light signals into visualized digital signals. These light-controlled soft switches exhibit strong photothermal responsiveness (~12 s), high programmability, and excellent cyclic stability (>500 times). This research provides a new perspective on light-controlled logic soft switches and their applications in logic circuits.

Current myocardial infarction (MI) treatment strategies remain challenged in suboptimal pharmacokinetics and potential adverse effects. Here we present a bioelectronic interface capable of producing on-demand abundant bioactive extracellular vesicles (EVs) near the MI area for in-situ localized treatment. The technology, termed electroactive patch for wirelessly and controllable EV generation (ePOWER), leverages wireless bioelectronic patch to stimulate embedded electrosensitive macrophages, actively modulating the biosynthesis of EVs and enabling EV production with high programmability to be delivered directly to the MI area. ~2400% more bioactive EVs were produced per cell under our ePOWER system. When surgically implanted, we demonstrate the therapeutic potential of in-situ EV production system to alleviate MI symptoms and improve cardiac function. This programmable ePOWER technology enables in-situ production of therapeutically rich EVs, thus reducing the need for exogenous cell expansion platforms and dedicated delivery, holding promise as a therapeutic all-in-one platform to treat various diseases.

Designing soft robots that are able to perceive unstructured, dynamic environments and their deformations has been a long-term goal. Previously reported self-sensing soft actuators were mostly constructed via integrating separate actuators and sensors. The actuation performances and the sensing reliability are affected owing to the unmatched materials and weak connections. Realizing a seamless integration of soft actuators and sensors remains a grand challenge. Here, we report a fabrication strategy to endow soft actuators with sensing capability and programmable actuation performances. The foam inside the actuator functions as actuator and sensor simultaneously, effectively addressing the conformability and connection reliability issues that existed in current self-sensing actuators. The actuators are lightweight (a decrease of 58% in weight), powerful (lifting a load of 433 times of its own weight), and versatile (coupling twisting and contraction motions). Furthermore, the actuators are able to detect multiple physical stimuli with high reliability, demonstrating their exteroception and proprioception capability. Two self-sensing soft robotic prototypes, including a bionic bicep and a bionic neck, are constructed to illustrate their multifunctionality. Our study opens up new possibilities for the design of soft actuators and has promising potential in a variety of applications, ranging from human-robot interaction, soft orthotics, to wearable robotics.

Multi-stimuli selective actuation of shape memory polymers (SMPs) with multi memory capabilities have attracted great attention in recent years, due to diverse active deformation application scenarios. Current multi-SMPs with low T t , however, are faced with inherent barriers, such as low fixation and inaccurate control, because the shape retainability, controllability, and responsiveness of SMPs are highly determined by transition temperature (T t ). Herein, quadruple-shape memory poly(aryl ether ketone) (PAEK) with tunable high T t and selective response characteristics were successfully fabricated for the first time, which especially harnessed ultra-high programmability and controllability. More significantly, the quadruple shape memory PAEK-based smart architectures such as “fingers” and “flower” were demonstrated to exhibit the controllable multi-stages actions. Utilizing a “man” as an example, we put forward different programming routes up to ten to make it perform complex pre-set deformation actions. The quadruple shape memory PAEK of high T t possessed great utilizing potential in fields of soft robots , actuators, and deformable devices.

Design of mechanical metamaterials with a negative Poisson's ratio (NPR), known as auxetics, is of great importance in the development of flexible electronics and tissue engineering. However, the mechanical performance of conventional auxetic metamaterials is largely hindered by the high porosity and lack of tunability, which restricts their practical engineering applications. Here, this study presents a programmable approach for designing integrated two-phase auxetic composite metamaterials with pore-free structure, robust interfaces, and customized mechanical properties by substituting the vacancy of the auxetic lattices (frame phase) with hydrogel-based soft fillers (matrix phase). Manipulated by two-phase stiffness contrast, integrated composite metamaterials exhibit a functional transition between auxetic and non-auxetic behaviors. Rationally designing Young's modulus ratios in spatial domains endows the programming of composite metamaterials with the desired spatial heterogeneity. Furthermore, the incorporation of temperature-responsive hydrogels to auxetic frames also enbles the development of dynamic programmable composites with the thermo-driven adaptability. As a practical application demonstration, designed programmable composites are used to dynamically tune the phononic bandgaps. The design strategy of integrated two-phase composite metamaterials paves the way for the development of advanced auxetic engineering materials with programmable mechanical properties, providing opportunity for conformal electronic patches, bio-scaffolds, and smart functionality applications.

There are more than 200 subtypes of human papillomavirus (HPV), and high-risk HPVs are a leading cause of cervical cancer. Identifying the genotypes of HPV is significant for clinical diagnosis and cancer control. Herein, we used programmable and modified DNA as the backbone to construct fluorescent genotyping nanodevice for HPV subtype distinction. In our strategy, the dye-labeled single-stranded recognize-DNA (R-DNA) was hybridized with Black Hole Quencher (BHQ) labeled single-stranded link-DNA (L-DNA) to form three functionalized DNA (RL-DNA). Through the extension of polycytosine (poly-C) in L-DNA, three RL-DNAs can be more firmly adsorbed on graphene oxide to construct reliable genotyping nanodevice. The genotyping nanodevice had low background noise since the dual energy transfer, including Förster resonance energy transfer (FRET) from dye to BHQ and the resonance energy transfer (RET) from dye to graphene oxide. Meanwhile, the programmability of DNA allows the proposed strategy to simultaneously and selectively distinguish several HPV subtypes in solution using DNA labeled with different dyes. To demonstrate clinical potential, we show multiplexed assay of HPV subtypes in cervical scrapes, and it has been successfully applied in HPV-DNA analysis in cervical scrapes samples. The genotyping nanodevice could be developed for simultaneous and multiplex analysis of several oligonucleotides in a homogeneous solution by adjusting the recognition sequence, demonstrating its potential application in the rapid screening of multiple biomarkers.

The introduction of dynamic covalent bonds (DCBs) endows liquid crystal elastomers (LCEs) with reprocessability while maintaining structural integrity, expanding their potential applications in advanced shape-morphing devices. Actuation stability of covalent adaptable LCEs is critical for prolonging service life; however, existing solutions may compromise reprocessability and reuse. Here, we propose a dual-catalyst strategy to achieve both long-term actuation stability and efficient programmability in covalent adaptable LCEs. A volatile catalyst and a thermal-latent catalyst are applied, each enabling transesterification but functioning independently in two sequential stages. In the first stage, stable actuation in the presence of the latent catalyst is realized, withstanding up to 10,000 cyclic actuation — significantly surpassing the maximum of 1,000 cyclic actuation reported in previous works. In the second stage, efficient reprocessability is achieved by activating the thermal-latent catalyst to release a strong base. Moreover, the spatial–temporal activation of the latent catalyst enables localized, gradient, and stepwise orientation. This strategy provides a novel solution to balancing the trade-off between actuation stability and reprocessability, which can also be extended to other covalent adaptable networks.

The rational design of mechanical metamaterials endows them with unusual properties inaccessible by conventional materials. In this study, compression–twist coupling building blocks with embedded chirality are fabricated by multimaterial 4D printing of shape memory polymers. Each chiral unit can be programmed individually by mechanical compression at a selected high temperature, whose temporary shape is self-maintained at the reduced temperature when the load is removed. With these building blocks, lattice-like architectures can be constructed in planar and layer-to-layer assemblies. Such modular design overcomes the limitation of conventional material arrangement by allowing on-demand re-programmability of chirality-defined structural heterogeneity. Using this strategy, metamaterials with tunable Poisson's ratio and shape-morphing metastructures are developed by harnessing the cooperative deformation of spatially heterogenous tessellation that undergoes local shrinkage or expansion, depending on the encoded Poisson response. An untethered multimodal soft gripper is assembled by chiral metastructures with distinct morphing modes, capable of unscrewing up a bottle cap attributed by the programmed functionality at module-level. The present modular chiral metamaterials with embedded chirality and flexible deployability may promote the applications of mechanical metamaterials in active shape-morphing structures and functional soft machines.
