A Multifunctional and Selective Ionic Flexible Sensor with High Environmental Suitability for Tactile Perception

Advanced Functional Materials, Год журнала: 2023, Номер 34(6)

Опубликована: Окт. 22, 2023

Abstract Inspired by the tactile sensory mechanism of human skin, ionic hydrogels‐derived flexible sensors have attracted much attention since they can produce output signals that match recognition mode nerves, showing a potential application in human‐machine interaction. Unfortunately, practical sensing properties hydrogels are restricted drawbacks hydroelastic instability and non‐selective response ability, such as poor mechanical strength, irretentive solvent retaining capacity, low‐temperature intolerance. Herein, this study, novel physical‐crosslink enhanced hydrogel‐PVA/PEG/TA‐MXene‐Na + /Li (PPM‐NL) nanocomposite is prepared shows well comprehensive strength (400% elongation at break, 0.93 MPa), electrical conductivity (8.1 S m −1 ), tear resistance, self‐healing anti‐freezing/drying features (93% water retention after sixty days frost resistance −27 °C). The PPM‐NL hydrogel‐derived sensor displays selective behavior to tensile compressive deformation with high sensitivity (G = 1.12) rapid time (only 60 ms). Further, device applied monitor joint motions humanoid hands integrated into manipulators recognize thickness softness objects, superior environmental stability. It be believed will provide inspiration for developing next‐generation biomimetic perception robots.

Biomimetic Micro-Nanostructured Evaporator with Dual-Transition-Metal MXene for Efficient Solar Steam Generation and Multifunctional Salt Harvesting

Nano-Micro Letters, Год журнала: 2025, Номер 17(1)

Опубликована: Янв. 6, 2025

Abstract Solar-driven interfacial evaporation is one of the most attractive approaches to addressing global freshwater shortage. However, achieving an integrated high rate, salt harvesting, and multifunctionality in evaporator still a crucial challenge. Here, novel composite membrane with biomimetic micro-nanostructured superhydrophobic surface designed via ultrafast laser etching technology. Attractively, double‐transition‐metal (V 1/2 Mo ) 2 CT x MXene nanomaterials as photothermal layer, exhibiting enhanced conversion performance due elevated joint densities states, which enables populations photoexcited carrier relaxation heat release, provides new insight into mechanism for multiple principal element MXene. Hence, MXene-200 can achieve rate 2.23 kg m −2 h −1 under sun, owing “light trap” effect, conversion, high-throughput water transfer. Synergetically, induce directed precipitation at edge, thus enabling harvesting recycling zero-emission brine water. Moreover, endowed excellent anti‐/de‐icing, anti-fouling, antibacterial, overcoming disadvantage that versatility difficult be compatible. Therefore, promising strategy hold great potential practical application solar evaporation.
