Prompting Interfacial Elastic Instability for Effective and Durable Icephobic Surfaces

open access: yesAdvanced Science, EarlyView.
To address the inherent trade‐off between icephobicity and the mechanical strength of icephobic materials, a new icephobic material design strategy is proposed by integrating fibrous construction frameworks and icephobic polymer. The structure prompts interfacial elastic instability and the subsequent undulatory interfacial stress at ice/solid ...

Bio‐Inspired Structural Color Irises as Physical Unclonable Functions for Anti‐Counterfeiting

open access: yesAdvanced Science, EarlyView.
This work employs colloidal photonic crystals to create macro‐to‐micro scale PUF anti‐counterfeiting patterns. Integrated with iris recognition algorithms, it establishes a multi‐layered optical anti‐counterfeiting system based on structural color irises.

A Generative AI‐Assisted Piezo‐MEMS Ultrasound Device for Plant Dehydration Monitoring

open access: yesAdvanced Science, EarlyView.
This study introduces a complementary metal–oxide–semiconductor (CMOS)‐compatible wearable piezoelectric micromachined ultrasound transducers (PMUTs) that sandwiches the leaf (PMUT–Leaf–PMUT, PLP) and employs generative artificial intelligence for real‐time analysis.

Stiffness‐Tunable Neurotentacles for Minimally Invasive Implantation and Long‐Term Neural Activity Recordings

open access: yesAdvanced Science, EarlyView.
A hydraulically actuated “Neurotentacle” probe offers tunable stiffness for precise implantation into the deep brain without rigid shuttles or dissolvable coatings. It stiffens during insertion to penetrate tissue and softens afterward to minimize damage and enable stable long‐term recordings.

Bionic Multimodal Augmented Somatosensory Receptor Enabled by Thermogalvanic Hydrogel

open access: yesAdvanced Science, EarlyView.
A skin‐inspired self‐powered multimodal fingertip receptor that integrates thermogalvanic hydrogels as active mechanoreceptors and thermoreceptors is proposed. By exploiting dynamic‐static thermovoltage of the hydrogel to visualize the unsteady interfacial heat conduction, different materials can be determined in 80 ms.
