Wearable strain sensors have aroused increasing interest in human motion monitoring, even for the detection of small physiological signals such as joint movement and pulse. Stable monitoring underwater a long time is still notable challenge, electronic devices can lose their effectiveness wet environment. In this study, superhydrophobic conductive knitted polyester fabric-based sensor was fabricated via dip coating graphene oxide polydimethylsiloxane micro/nanoparticles. The water contact angle obtained sample 156°, which retained above 150° under deformation (stretched to twice original length or bent 80°). Additionally, exhibited satisfactory mechanical stability terms superhydrophobicity conductivity after 300 abrasion cycles 20 accelerated washing cycles. sensing performance, showed rapid obvious response different deformations vibration, finger bending, droplet shock. With good combination conductivity, well wearability stretchability fabric, wireless connected with Bluetooth allow remote sports, e.g., swimming, raise an alert drowning conditions.

Biological Tissue-Inspired Ultrasoft, Ultrathin, and Mechanically Enhanced Microfiber Composite Hydrogel for Flexible Bioelectronics

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Май 28, 2023

Hydrogels offer tissue-like softness, stretchability, fracture toughness, ionic conductivity, and compatibility with biological tissues, which make them promising candidates for fabricating flexible bioelectronics. A soft hydrogel film offers an ideal interface to directly bridge thin-film electronics the tissues. However, it remains difficult fabricate a ultrathin configuration excellent mechanical strength. Here we report tissue-inspired ultrasoft microfiber composite (< 5 μm) film, is currently thinnest as far know. The embedded microfibers endow prominent strength (tensile stress ~ 6 MPa) anti-tearing property. Moreover, our capability of tunable properties in broad range, allowing matching modulus most tissues organs. incorporation glycerol salt ions imparts high conductivity anti-dehydration behavior. Such hydrogels are constructing attaching-type bioelectronics monitor biosignals.

Environmental Stability Stretchable Organic Hydrogel Humidity Sensor for Respiratory Monitoring with Ultrahigh Sensitivity

Advanced Functional Materials, Год журнала: 2024, Номер 34(38)

Опубликована: Май 3, 2024

Abstract Real‐time monitoring of respiration plays a very important role in human health assessment, especially and analyzing during exercise sleep. However, traditional humidity sensors still have problems flexibility, sensitivity, durability, so there is an urgent need to develop with high stretchability, environmental resistance as respiratory applications. Here, based on the double network hydrogel structure polyvinyl alcohol polyacrylamide, highly sensitive, stretchable, environmentally stable organic sensor has been manufactured by using synergistic effect lithium chloride MXene. The shows rapid response range 40–85% RH, sensitivity −103.4%/% RH. In addition, it exhibits more than 3000% mechanical strain excellent resistance, which attributed chemical cross‐linking multiple hydroxyl groups glycerol forming rich hydrogen bonds water polymer chains. used for real‐time breathing sleep processes. This work provides new strategy preparing high‐performance, extensibility, stability hydrogel‐based monitoring.

Cylindrically symmetric cholesteric liquid crystal elastomer (CLCE) fibers templated by tubular confinement are reported, displaying mechanochromic, thermochromic, and thermomechanical responses. The synthesis inside a sacrificial tube secures radial orientation of the helix, ground state retroreflection wavelength is easily tuned throughout visible spectrum or into near-infrared varying concentration chiral dopant. display continuous, repeatable, quantitatively predictable mechanochromic response, reaching blue shift more than -220 nm for 180% elongation. cylindrical symmetry renders response identical in all directions perpendicular to fiber axis, making them exceptionally useful monitoring complex strains, as demonstrated revealing local strain during tying different knots. CLCE reflection color can be revealed with high contrast against any background taking advantage circularly polarized reflection. Upon heating, respond-fully reversibly-with red expansion/axial contraction. However, there no transition an isotropic state, confirming largely forgotten theoretical prediction de Gennes. These easy way may open new windows large-scale application advanced wearable technology beyond.
