A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

open access: yesAdvanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

open access: yesAdvanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Additive‐Free Ti3C2Tx MXene Actuator with Large Deformation, Programmability, and High‐Humidity Stability via Precise Interlayer Spacing Control Engineering

open access: yesAdvanced Science, EarlyView.
By sequentially assembling MXene nanosheets with significant size differences, a multistimulus responsive additive‐free MXene actuator with gradient structure is obtained. An innovative cyclic low‐temperature annealing‐rehydration technology is proposed, which achieves precise control of interlayer d‐spacing, initial shape, and actuation behavior of ...

A Microfluidic Digital Shutter of Liquid–Liquid Interface for Fabrication of Multifaceted Hydrogel Microfiber Structure

open access: yesAdvanced Science, EarlyView.
A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.
