Future metrology: are you ready for the digital age?

Sascha Eichstädt“Coordination Digitalisation”

Sascha Eichstädt2

“When wireless is perfectly applied, the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole...and the instruments through which we shall be able to do this will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.” Nikola Tesla, 1926

“I think there's a world market for maybe five computers.”Thomas Watson, CEO IBM, 1943

Data without correct metadata is useless

Measurement data without units is dangerous

Digitalisation in the SI: from paper to digitalSI brochure, Section 5: Writing unit symbols and names, and expressing the values of quantities

• “Compliance with these rules and style conventions […] supports the readability of scientific and technical papers.”

• upright type regardless of the type used in the surrounding text• printed in lower-case letters unless they are derived from a proper name• avoid ambiguities, for example by using brackets or negative exponents

SI prefix SI unit Exponentoptional optional

Digitalisation in the Quality Infrastructure

Digitalisation in the Quality Infrastructure

Products• Complex devices and systems• Embedded computing• “Smart” features

Services• “X as a service”• Cloud platforms • AI-based solutions

Regulations• AI: ethics, confidence and trust• Technological enforcement

Digitalisation in the Quality Infrastructure

• Keeping up with increasing pace of industry and society

• End-to-end collaborative, digital standardisation

• Machine-executable digital standards

• Integration into (automated) digital processes

• Keeping up with increasing pace of industry and society

• Digital services and accreditation for novel concepts (e.g. lot size 1)

• Machine-executable digital certificates

Guiding principles

12 Sascha Eichstädt

Ensuring the uniformity of measurements in a digitised world and confidence in data and algorithms.

• Machine-interpretable information throughout the data lifecycle

• Machine-executable digital certificates

• Metrology for Internet of Things (IoT) - also in legal metrology

• Numerical simulations as virtual measurements

Guiding principles

13 Sascha Eichstädt

• Research data management in line with the FAIR principles

• Software quality framework and open-source development

• Reference data sets for method assessment and data curation

• Consistent use of metadata and vocabulary

Metrology as anchor of trust in Open Science and data-driven research.

Guiding principlesHolistic approach for the treatment of measuring instruments and measurement data

14 Sascha Eichstädt

• Consistent concepts from legal to industrial metrology

• "Metrology by design" for confidence measured values

• Consideration of the entire life cycle of a measuring instrument

• Concepts that scale with the number of measuring instruments
