Geohazard Strain Monitoring Mitigates Risk for Oil Pipelines

Mitigating the risks associated with oil pipeline faults provides increased reliability, reduced downtime and lower maintenance costs, leading to increased revenues. However, pipelines are naturally vulnerable to operational, environmental and man-made issues such as internal erosion and corrosion, mechanical deformation, leaks and encroachments. Compounding the risks, the actual detection and localization of incipient and advanced faults in pipelines is a very difficult, expensive and imprecise…Read More

Measuring Strain and Temperature within 3D Printed Components

Alternative vehicles that utilize 3D printed components face unique challenges with manufacturing and model validation. To advance the understanding of such applications, Local Motors and Luna Innovations embedded high definition fiber optic sensors within structures made with a large-scale area manufacturing machine to provide distributed strain and temperature measurements during and after the printing process. Luna engineers performed experiments to determine how altering the print…Read More

How to Monitor for Rapid Temperature Increases in Battery Cells

The optimal function of Li-ion batteries is confined to restrictive temperature and voltage windows. Internal faults can initiate heating, triggering a positive feedback loop that results in thermal runaway. The worst case scenario resulting from this is an explosive hazard and potential harm to lives. Current monitoring techniques are generally limited to battery management systems that utilize a few discrete single-point sensors. Scaling up of…Read More

Self-Driving Vehicles: Evaluating Damage and Wear with Smart Parts

Fiber optic sensors have unique characteristics such as their low profile, flexibility and resistance to chemicals and corrosion that make them uniquely suited for long-term and embedded applications. This creates an opportunity for a design to incorporate “smart parts” that can easily communicate their health to an inspector. Instead of relying on visual confirmation or disassembly of the vehicle to check on hard-to-get-to structural elements,…Read More

Creating a Self-Measuring Smart Structure with a Fully Distributed Strain Rosette

With the integration of new materials into applications and structures, developing strain profiles to characterize material behavior, conduct structural health monitoring and enable in-situ non-destructive testing requires a different measurement solution. High-Definition Fiber Optic Sensors (HD-FOS) have been frequently utilized for highly spatially-resolved strain measurements on a wide variety of materials and complex part geometries. Luna has demonstrated that a single fiber can be configured…Read More

TeraMetrix Shares Terahertz Advantages with the Conversion Industry

In April the TeraMetrix team attended the ICE 2019 (International Converting Exhibition) in Louisville, Kentucky. The conference provided an opportunity for our team to share the advantages of terahertz technology and what it could provide for conversion applications. Conversion, as might be implied by the name, refers to the process of converting one product into another.  For example, coating adhesive on a piece of paper,…Read More
