Analysis of Polyimide-Coated Optical Fiber Long-Period Grating-Based Relative Humidity Sensor

, 2013
A long-period grating (LPG)-based relative humidity (RH) sensor is developed, based on using a tailored layered polyimide coating on the grating region at the distal end of the fiber probe and allowing it to respond to humidity changes.

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Optimization of sensitivity in Long Period Fiber Gratings with overlay deposition

Optics Express, 2005
The deposition of an overlay of higher refractive index than the cladding in a Long Period Fiber Grating (LPFG) permits to improve the sensitivity to ambient refractive index changes in a great manner. When the overlay is thick enough, one of the cladding modes is guided by the overlay.

Skin‐Conformal Myography for Real‐Time Hand Tracking Using a Laser‐Induced Graphene Strain Sensor Array

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A skin‐conformal wearable device based on laser‐induced graphene is developed for continuous strain measurement across the circumference of the forearm for gesture recognition and hand‐tracking applications. Post material optimization, the strain sensor array is integrated with a wearable wireless readout circuit for real‐time control of a robotic arm,

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]

, 2000
We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...

Optimizing Anatomic Reduction of Vertical Meniscus Tears With All‐Inside Meniscus Repair

Arthroscopy Techniques, EarlyView.
Abstract The lateral and medial meniscus play vital roles in load distribution across the knee joint and in the prevention of knee osteoarthritis. As such, every effort should be made to save and repair the meniscus when possible, as partial and total meniscectomies have been shown to impair the meniscus’ ability to effectively dissipate shock ...

Differential phase tracking applied to Bragg gratings in multi-core fibre for high accuracy curvature measurement [PDF]

, 2006
High resolution quasi-static and dynamic curvature measurements are made by differential interferometric phase measurement of fibre Bragg gratings in separate cores of a multi-core fibre.

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.
