Average Number of Significant Modes Excited in a Mode-Stirred Reverberation Chamber [PDF]

open access: yes, 2014
International audienceAlthough the number of significant modes is intuitive, this concept has never been clearly defined, and this, mainly because of the unbound number of modes involved in modal overlap. In the present paper, we show that, for a perfect

Solution‐Like Water Transport Across Molecular to Macroscopic Length Scales in Crosslinked Poly(Ethylene Glycol Diacrylate) Networks With Tailored Sidechains

open access: yesJournal of Polymer Science, Volume 63, Issue 19, Page 3990-4002, 1 October 2025.
Cross‐linked PEGDA network microparticles are synthesized with spin labels to sense local water motion. From the nanoscale to the macroscale, PEGDA exhibits rapid, solution‐like water transport as measured by spectroscopic techniques. Addition of side chain chemistries further modulates local water diffusion.

Transforming Plastic Waste into Strain Sensors: Multifunctional Upcycled TPEE Elastomers with MXene Multilayer Assemblies

open access: yesAdvanced Materials Technologies, Volume 10, Issue 17, September 4, 2025.
A sustainable approach is reported for upcycling PET waste into thermoplastic polyester elastomer (TPEE)‐based films with advanced properties, specifically designed for applications in strain sensing, conductivity, and photothermal response. Through a layer‐by‐layer deposition technique, TPEE films are fabricated with bio‐compatible chitosan (CH) or ...

MEMS: The Sensory Nervous System for Embodied AI Robots

open access: yesSmartBot, Volume 1, Issue 3, September 2025.
Embodied AI represents a shift of intelligence from virtual to physical realms, calling for efficient and multimodal perceptual capabilities. This review illustrates how Micro‐Electro‐Mechanical Systems (MEMS) offer miniaturized, low‐power sensors such as those for ranging, inertia, touch, sound and smell, which serve as robotic “sensory organs”.

Regionally resolved cardiac metabolism using a dipole‐loop array coil for 7 T 31P‐MRSI

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 2, Page 480-496, August 2025.
Abstract Purpose We introduce a novel commercial phosphorus‐31 (31P) dipole‐loop array coil, describing the coil hardware and testing its performance on phantoms. We used this coil to assess cardiac metabolism per region in healthy volunteers. Methods B1+ field maps were simulated and compared to maps measured with a set of CSI sequences with varying ...

A shielded 32‐channel body transceiver array with integrated electronics for 7 T

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 2, Page 852-866, August 2025.
Abstract Purpose Develop a 32‐channel transceiver array for 7 T body imaging that incorporates an RF shield, improves SNR, lowers g‐factors, and is robust to external loading. Methods The addition of a local RF shield was first investigated for single resonant blocks consisting of either one loop and a dipole (LD) or three loops and a dipole (3LD).
