Electrospun Lignin/ZnO Nanofibrous Membranes for Self‐Powered Ultrasensitive Flexible Airflow Sensor and Wearable Device

open access: yesAdvanced Materials, EarlyView.
This study explores the novel sensing applications of water evaporation‐induced power generation, by using lignin/ZnO nanofibrous membranes for sensing airflow through output voltage variation. Obtained lignin/ZnO airflow sensors are self‐powered, precise, and quick‐responding, and can be used as wearable devices for breath monitor, surrounding ...

Directionally Modulated Zinc Deposition by a Robust Zincophilic Cu‐Phthalocyanine Protective Layer in Dendrite‐Free Aqueous Zinc Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Benefiting from the precisely anchored zincophilic sites, the ample transport channels with rich redox active sites, and the suppressed hydrogen evolution by the copper (Cu) sites, a highly conjugated robust Cu‐Phthalocyanine covalent organic framework layer is designed and applied for directional modulation of zinc (Zn) ions and dendrite‐free Zn ...

Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

open access: yesAdvanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.

Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.
