A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

open access: yesAdvanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Laser‐Induced Graphene Cantilever Airflow Sensor Fabricated via Laser Cutting and Folding a Copper–Polyimide Film

open access: yesAdvanced Sensor Research, EarlyView.
This study presents a single‐axis airflow sensor featuring a vertically standing laser‐induced graphene (LIG) cantilever on a polyimide substrate. Fabricated entirely using a fiber laser, the sensor integrates surface‐mounted circuits and demonstrates a quadratic response to airflow between −10 and 10 m s−1, offering a simple and scalable approach to ...
