Since ancient times, humans have measured different things and the units of measurement have been more or less regulated. A few years ago, it was time for the latest change, but why was it made and what does it mean today and in the future?

In this seminar, we will partly provide a background to today's measurement system, but above all give a motivation for and future perspectives on the definitions that today form the basis of our measurements, everyday as well as advanced.

The cost of your own booked digital lecture, about an hour long incl. question time/discussion, is 8 715 SEK regardless of how many you are. The lectures are also offered in English.

At this seminar, we will tell you more about why we measure, the importance of good measurements and what is really meant by good measurements.

Here is a brief introduction about quality assurance of measurement results with ISO 17025. How should you and your laboratory work to deliver reliable measurement results to customers? And for those who order measurements: how do the laboratories work to ensure that you can trust the measurements you order?

One way is to look at how you work from receiving an assignment, via the actual measurement and delivery, to how you follow up customer satisfaction. For all steps, you need to ensure that you have the right processes and skills. There is an established international "best practice" for how this can be done, and it is described in the ISO 17025 standard.

Optical fiber coatings are essential for the performance and reliability of the optical fiber in application. For most applications, standard coatings such as acrylates and polyimides are used, providing good protection against mechanical and chemical ambients. For high temperature applications, up to 300°C, polyimide coatings are industrial standard. 

In this project, funded by the Swedish innovation program SIO Graphene, we developed methods to coat long lengths of optical fiber with graphene/polyimide nanocomposite (NC) coatings. Several properties of the as-coated fibers proved interesting for sensor applications, as validated in the project.

• The NC coated fibers are (slightly) more robust against high temperature ageing in air, with the fiber strength retained longer than standard polyimide coated fibers. 
• The NC coating is electrically conductive (kOhms/cm) and can be used for heating the fiber. 
• The NC coated fibers show significantly less moisture-induced strain than standard polyimide coated fibers. This is particularly important for FBG-sensor applications. 

The project has shown, for the first time, the production of long length optical fibers with polyimide coating enhanced by the integration of graphene and graphene oxide particles. Further exploration of this, and other nanocomposite coatings, is on-going at RISE. Reach out if you're interested in collaborating on this topic!

Many factors affect measurements: the human factor, temperature, humidity, what we measure, what measuring instrument we use, and so on. But no matter how good the measuring instruments we use or how ideal the conditions are, there is no way to know that the measurement value we have received is completely true.

We talk about what factors affect measurements and how to think about the level of measurement uncertainty.

Maybe your colleagues missed a seminar that you think would benefit them. Or perhaps you need an external speaker for a development day or similar occasion. Now you can book a private seminar with one of our presenters. In addition to the talks offered as open seminars, we also provide a few others.

The seminars are aimed at those who want to learn more about how, for example, we ensure that a meter is indeed a meter worldwide, and how quality-assured metrology contributes to the functioning of international research, trade, and production.

The cost for a private booked digital lecture, approximately one hour including Q&A/discussion, is SEK 8,715 regardless of the number of participants. The lectures are also offered in English.

Of course, we can also create a seminar tailored to your specific needs. Please contact us for pricing information on customized seminars.
