Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Digital Reading Environment: Instrumentation of the scholarly reading activity on digital devices

open access: yes, 2008
Nos travaux de recherche portent sur l'instrumentation de la lecture savante, lecture intensive dont le but est de produire un nouveau contenu qui réifie l'interprétation d'un corpus par un lecteur. Malgré l'émergence d'une culture numérique, le papier reste le support privilégié de cette pratique.

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

open access: yesAdvanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Digital reading strategies in computer English

open access: yes, 2007
This paper focuses on the use of web-based discourse by three Spanish undergraduate students in Computer Engineering. Key lexico-grammatical features in Computer English have been analysed by means of corpus linguistics techniques, for which word ...

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

open access: yesAdvanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Factors Influence Reading From Screen of Arabic Textbook for Learning by Children Aged 9 to 13

open access: yes
The problem with e-texts are related to the way texts are displayed on a screen, with multiple and different aspects that affect legibility, making readers prefer to read a paper format rather than e-resources.
