Conformable core-shell fiber tactile sensor by continuous tubular deposition modeling with water-based sacrificial coaxial writing

Gas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

Synthesize and Characterization of Hollow and Core/Shell Based on CeO2 as a Alcohol Sensor

In this study, CeO2 hollow spherical nanoparticles, CeO2/SiO2 @ CeO2 core/shell composites,and hollow CeO2/SiO2 sensors were synthesized and their microstructures were researched byFT-IR, XRD, FESEM, EDX and BET analyses. The peaks observed in the FT-IR spectra of the synthesizedsamples corresponded to Ce-O stretching vibration (ca. 566 cm-1) and O-Si-O bendingvibration (ca. 470 cm-1). XRD diff...

Water-core Fresnel fiber.

A water core photonic crystal Fresnel fiber exploiting a hole distribution on zone plates of a cylindrical waveguide was developed and characterized. This fiber has similar guiding properties as the pristine air-hole guiding fiber although a large loss edge ~900nm is observed indicating that the bandgap associated with Fresnel guidance has shifted to longer wavelengths. The absorption bands of ...

Facile synthesis 3D flexible core-shell graphene/glass fiber via chemical vapor deposition

UNLABELLED Direct deposition of graphene layers on the flexible glass fiber surface to form the three-dimensional (3D) core-shell structures is offered using a two-heating reactor chemical vapor deposition system. The two-heating reactor is utilized to offer sufficient, well-proportioned floating C atoms and provide a facile way for low-temperature deposition. Graphene layers, which are control...
