The document summarizes the Medfiber project, which aims to develop a non-invasive fiber optic probe for urinary incontinence diagnosis. The current methods are invasive, inconclusive, and expensive. Medfiber would be catheter-free, have high accuracy, and reduce hospitalization costs. It combines interferometric fiber optic sensor technology with a disposable all-in-one probe. The founders describe the market opportunity, business model, sales and marketing plan, team, and project milestones. Their projections estimate the company could reach over 3 million Euros in net income within 5 years if scalability goals are met.
The document summarizes the projects of the Optical Fibre Sensors Research Centre at the University of Limerick. It describes projects involving biomedical sensors, radiation therapy dosimetry sensors, gas and pressure monitoring, food monitoring, and structural health monitoring of historical buildings. It also outlines collaborations with universities and companies in Italy and China on fiber optic sensor technologies.
The document summarizes the projects of Daniele Tosi and the Optical Fibre Sensors Research Centre at the University of Limerick. Some key projects discussed include developing extrinsic Fabry-Perot interferometer sensors for biomedical applications like measuring pressure for urodynamics and cardiovascular applications. The research has also led to developing optical fibre sensors for monitoring radiation levels in radiation therapy. Partnerships with hospitals and other universities in Italy and China are also mentioned.
This document describes a miniature low-cost extrinsic Fabry-Perot interferometer for measuring low pressures. It consists of a diaphragm attached to an optical fiber that changes the air gap when subjected to pressure variations. This allows accurate measurement of pressures below 1 mmHg. The sensor is smaller, lighter, and lower cost than existing pressure sensors. It was tested in burette and heart simulator experiments demonstrating high accuracy below 1 mmHg and stability over long periods.

This document summarizes optical fiber sensor research activities at the University of Limerick for medical applications. The research center develops various optical fiber sensor technologies including EFPI, FBG, and LPG sensors for minimally invasive pressure, temperature, and strain monitoring. These sensors have applications in cardiovascular monitoring, urodynamics, robotic surgery, and radiofrequency ablation. Partnerships with medical centers help translate the fiber sensor technologies to solutions for fractional flow reserve measurement, ventricular assist devices, and bladder outlet obstruction diagnosis.

Daniele Tosi has an academic background in telecom engineering and electronics engineering. He has industrial experience and is currently a postdoc focusing on university spin-offs. His research plan focuses on developing a "Lab-in-a-fiber" architecture using fiber Bragg gratings and evanescent field sensing to create distributed, low-cost sensors for strain, temperature, and biochemical measurements. His goals are to improve sensor performance and lower costs over 4 years, working with technology partners and pursuing commercialization through technology transfer and potential spin-off.
The document discusses Intelligent Fiber Bragg Gratings (IFBG), which are fiber optic sensors embedded in optical fiber that can sense multiple physical parameters. IFBG prototypes have been developed in-house that are cheaper than existing solutions. IFBGs use Fiber Bragg Gratings (FBG) and can be multiplexed into arrays and interrogated using different architectures involving switches, lasers, and photodiodes. Potential applications include structural health monitoring of composites.

This document describes a low-cost miniature fiber-optic sensor for cardiovascular pressure measurement based on an extrinsic Fabry-Perot interferometric (EFPI) design. The EFPI sensor uses a fiber optic diaphragm attached to a capillary and fiber Bragg grating to measure pressure changes. It offers high accuracy below 1 mmHg, small size, low invasiveness, and immunity to electromagnetic interference. Testing showed the sensor achieved accuracy of 0.2 mmHg, stability of 0.6 mmHg/hr, and successfully measured pressure waves in heart simulator and ventricular assist device experiments.

This document discusses fiber optic sensors and opportunities for improving their commercial viability. It begins with an overview of the technology, highlighting fiber optic sensors' superior performance, small size, distributed sensing capabilities, and safety.

The document proposes a "lab-in-a-fiber" approach using microfluidics to develop low-cost, plug-and-play fiber optic sensors that can measure multiple parameters like strain, temperature, pressure, chemicals, and biomedical readings. This would help address key issues currently restricting the technology's growth and enable broader real-world deployment.
