Medicine in Blink

Journal of the American College of Cardiology, 2007
![Figure][1] The practice of medicine is certainly one of the most cerebral undertakings in the world. It is preceded by 4 years of medical school in which an enormous information base is accumulated. Residency and specialty training entail further reading and education.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Don’t Blink at the Wrong Time: Smart Glasses Inducing Timely Blinks

IEEE Access
Blinking is essential for eye health, but its frequency decreases during concentration-intensive tasks, such as using Visual Display Terminals (VDTs) or playing musical instruments, potentially leading to dry eye syndrome.

A Mixed-Methods Approach Using Self-Report, Observational Time Series Data, and Content Analysis for Process Analysis of a Media Reception Phenomenon

Frontiers in Psychology, 2019
Due to the complexityof research objects, theoretical concepts, and stimuli in media research, researchers in psychology and communications presumably need sophisticated measures beyond self-report scales to answer research questions on media use ...

Aptamer‐Based Delivery Systems for VEGF and NGF Modulation in Ocular Therapies

Advanced Healthcare Materials, EarlyView.
Aptamer‐based delivery systems targeting NGF and VEGF hold significant potential for precise and sustained treatment of complex diseases affecting both the anterior and posterior segments of the eye. This review critically summarizes current strategies for NGF and VEGF delivery as well as VEGF sequestration, providing a clinical perspective on how ...

Spontaneous blinking and brain health in aging: Large-scale evaluation of blink-related oscillations across the lifespan

Frontiers in Aging Neuroscience
Blink-related oscillations (BROs) are newly discovered neurophysiological brainwave responses associated with spontaneous blinking, and represent environmental monitoring and awareness processes as the brain evaluates new visual information appearing ...

Theory and effectiveness analysis of dual-aircraft formation active cancellation slow synchronous blinking jamming

AIP Advances, 2023
Dual-aircraft formation slow synchronous blinking jamming is standard for jamming monopulse tracking. However, the jamming signal ratio (JSR) of slow synchronous blinking jamming is low and fluctuant in a dynamic jamming scenario, which leads to a poor ...

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

Advanced 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.

Rapid Voluntary Blinking as a Clinical Marker of Parkinson’s Disease

Journal of Parkinson’s Disease
Reduced spontaneous blinking is a recognized Parkinson’s disease (PD) feature. In contrast, voluntary blinking has been less studied and might serve as a measurable marker of facial bradykinesia. We tested 31 PD patients and 31 controls.
