Intrinsic, multiplexable sensors for electric field strength using structural slow light in phase-shifted fibre Bragg gratings [PDF]

, 2012
In this paper we demonstrate through simulation the potential for phase-shifted fibre Bragg gratings incorporating structural slow light to enable intrinsic reflection-mode point sensors for electric field or voltage.

Centralization Design and Erosion Simulation of Electric Submersible Pump in Inclined Well

Shiyou jixie, 2020
When the electric submersible pump unit is applied for oil production in inclined wells, the deformation of the electric pump unit due to the lateral force component will change its gap with the casing and even cause contact friction.

UNLOADED OIL-SUBMERSIBLE CABLE REDUCED DYNAMIC MODEL ORDER OPTIMIZATION BASED ON THE FREQUENCY RESPONSE APPROXIMATION

Известия Томского политехнического университета: Инжиниринг георесурсов, 2021
The relevance. An oil-submersible cable transfers electrical energy from an energy source to submersible electric motors of oil production plants. Resonant peaks localized in a narrower frequency band characterize the frequency response of an unloaded ...

Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
