Abstract Highly conductive and stretchable fibers are crucial components of wearable electronics systems. Excellent electrical conductivity, stretchability, wearability required from such fibers. Existing technologies still display limited performances in these design requirements. Here, achieving highly sensitive strain sensors by using a coaxial structure, prepared via wet spinning thermoplastic elastomer‐wrapped carbon nanotube fibers, is proposed. The attain high sensitivity (with gauge...
Abstract The fast development of wearable electronic systems requires a sustainable energy source that can harvest from the ambient environment and does not require frequent charging. Piezoelectric polymer films are perfect candidate for fabricating piezoelectric nanogenerators (PENGs) to mechanical due their flexibility, good piezoelectricity, environmental‐independent stable performance because inherent polarization. However, most applications limited pressing mode harvesting is based on...

Abstract The widespread adoption of renewable and sustainable elastomers in stretchable electronics has been impeded by challenges their fabrication lacklustre performance. Here, we realize a printed conductor with superior electrical performance synthesizing recyclable vegetable oil polyurethane (VegPU) elastomeric binder developing solution sintering method for composites Ag flakes. impedes the propagation cracks through its porous network, while reaction reduces resistance increment upon...
Abstract Fiber‐based artificial muscles are promising for smart textiles capable of sensing, interacting, and adapting to environmental stimuli. However, the application current muscle‐based in wearable engineering fields has largely remained a constraint due limited deformation, restrictive stimulation, uncomfortable. Here, dual‐responsive yarn with high contractile actuation force fabricated by incorporating very small fraction (<1 wt.%) Ti 3 C 2 T x MXene/cellulose nanofibers (CNF)...
Abstract Conductors that can sustain large strains without change in resistance are highly needed for wearable electronic systems. Here, the fabrication of stretchable coaxial fiber conductors through self‐buckling conductive polymer ribbons inside thermoplastic elastomer channels, using a “solution stretching–drying–buckling” process, is reported. The unique hierarchically buckled and core axial direction makes very stable, with less than 4% when applying as much 680% strain. These fibers...
Stretchable temperature sensors are critical components in soft robotics.
This study introduces advancements in electrohydrodynamic (EHD) pumps and the development of a 3D-printable anti-swelling organohydrogel for soft robotics. Using digital light processing (DLP)technology, precise components with less than 1% size variation are fabricated, enabling unique manifold pump array. design achieves an output pressure 90.2 kPa-18 times higher traditional configurations-and flow rate 800 mL min
Highly stretchable strain sensors are key elements of new applications in wearable electronics and soft robotics. Most the available technologies only measure positive (stretching), cannot negative strains (compression). We propose here a technology that enables measurement both with high sensitivity. A carbon nanotube paper is pre-cracked to introduce well-controlled network open cracks as sensing element; then, sandwiched by thermoplastic elastomer. The resulting sensor also pre-stretched...
Abstract Chemical sensors detect a variety of chemicals across numerous fields, such as automobile, aerospace, safety, indoor air quality, environmental control, food, industrial production and medicine. We successfully assemble an alcohol-sensing device comprising thin-film sensor made graphene nanosheets (GNs) bacterial cellulose nanofibers (BCNs). show that the GN/BCN has high selectivity to ethanol by distinguishing liquid–phase or vapor–phase (C 2 H 6 O) from water (H intelligently with...
Mechanical assessments of skeletal muscles have profound relevance in the clinical diagnosis, management, and treatment neuromuscular diseases. Current measures muscular biomechanics involve either non-instrumental methods that are subjective qualitative or bulky instruments with limited accessibility. Here, we develop a wearable device integrates pneumatic actuator piezoelectric sensor for vivo measurements elasticity, where machine learning models adopted to evaluate severity The conforms...
Aggregation is a major problem for hydrophobic carbon nanomaterials such as nanotubes (CNTs) in water because it reduces the effective particle concentration, prevents particles from entering medium, and leads to unstable electronic device performances when colloidal solution used. Molecular ligands surfactants can help disperse, but they tend degrade electrical properties of CNTs. Therefore, self-dispersed without need surfactant are highly desirable. We report here, first time our...
