Stress Monitoring for Anchor Rods in Subway Tunnel Using FBG Technology

October 19th, 2015|

Structural health monitoring is an integral part of civil engineering and is also used frequently as a diagnostic tool to detect or infer the presence of defects and determine when maintenance operations are needed. Some common techniques used today to assess the health of civil structures include ultrasonic scanning, transient pulse and infrared thermography and ground radar. However, these techniques have limitations in that they are not suitable for real-time, in situ assessment of structures. [...]

Register for Micron Optics Partner Training Program in May

October 16th, 2015|

Register now to join us at Micron Optics’ headquarters in Atlanta, Georgia, USA on May 13-15  for our hands-on fiber-optic sensing and product training program. This exciting program is aimed at ensuring any user of our fiber optic sensing technology has the tools and resources needed to successfully deploy a fiber-optic sensing solution. The course is aimed specifically at our system integrators and channel partners, but is open to any parties or individuals interested in [...]

FBG Sensors in the Geotechnical Centrifuge

October 16th, 2015|

This week’s blog post by: Talia da Silva, PhD Student, University of Cambridge, United Kingdom In the civil engineering industry and research, fibre optic sensors are widely used in the field of structural health monitoring.  The versatility of FBG sensors allows for their use in a large range of applications, and we at the University of Cambridge are looking to incorporate them into the monitoring of physical models in geotechnical centrifuges. Geotechnical centrifuges are used [...]

Wind Turbine Tower Structural Health Monitoring Using FBG Technology

October 16th, 2015|

Due to the high initial implementation costs of wind energy, increasing the longevity of the entire turbine system plays a crucial role in contributing to the economic sustainability of wind energy projects. A main component of a wind turbine system is the structure’s supporting tower that is costly and difficult to repair and even more costly and difficult to replace. To combat this issue, structural health monitoring (SHM) is employed to identify problems within the [...]

Autonomous Sensing-Healing System Developed for Large-Scale Composite Structures Using Fiber Optic Sensors

October 16th, 2015|

Inspired by biological systems that are able to heal after being wounded, various self-healing materials have recently been investigated in order to develop the first autonomous sensing-healing system applicable to large-scale composite structures. In a paper by Shu Minakuchi from the Department of Advanced Energy at the University of Tokyo, et al., delamination infiltration tests are carried out to confirm the feasibility of a hierarchical fiber-optic-based delamination detection system combined with a microvascular self-healing material. [...]

FBG Technology Used in Shape Sensing for Continuum Robots

October 16th, 2015|

Continuum robots are ideal for applications such as minimally invasive surgery due to their continuously bending, curvilinear structure that enables them to maneuver through anatomical spaces in a snake-like manner. However, their flexibility can lead to uncertainty in the shape of the robot’s backbone curve as well as the location of the tip. To address this issue, researchers from Harvard Medical School investigated a potential, more promising technique employing the use of a Micron Optics [...]
