A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication

open access: yesAdvanced Science, EarlyView.
A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.

Chirality Regulates Stem Cell Fate and Promotes Corneal Epithelial Regeneration via Manipulating Notch Pathway

open access: yesAdvanced Science, EarlyView.
Chirality governs the limbal epithelial stem cell fate. Right‐handed chirality enhances cell proliferation and differentiation, while left‐handed chirality partially maintains cell stemness. By activating the Notch pathway, 3D right‐handed chiral hydrogel offers a drug‐free and cell‐free strategy for effective corneal regeneration.
