editorial D ear Readers, I wish you a very warm welcome to this second special issue of the Magazine on "Instrumentation and Measurement in 2020." Along with the previous Part A issue, this issue aims to celebrate Instrumentation and Measurement in 2020 by highlighting challenging subjects in the field. In particular, we will read about "the impact of the new International System of Units in the measurement sector," "Artificial Intelligence applied to Instrumentation and 2 Measurement," "Evolution of Sensors in the last ten years" and "Advanced Measurement Systems." These subjects fill the pool of topics which are typically addressed by the Magazine, which aims to highlight Open Problems and Hot Topics in the Instrumentation and Measurement framework. I would really like to thank all of the colleagues who have contributed to the realization of this second volume of the special issue on "Instrumentation and Measurement in 2020," providing unique readings on such amazing subjects. Enjoy your reading, IEEE Instrumentation & Measurement Magazine September 2020
