A participação do Laboratório Nacional de Metrologia do IPQ no desenvolvimento da Metrologia Elétrica Europeia
O Laboratório Nacional de Metrologia do IPQ, enquanto membro da EURAMET – The European Association of National Metrology Institutes, tem participado ativamente em projetos de investigação internacionais, com vista ao desenvolvimento da metrologia europeia, nos diferentes domínios técnico- científicos e de forma a responder às prioridades estabelecidas pelas agendas estratégicas europeia e nacional relativamente ao suporte da metrologia na competitividade da economia, na proteção ambiental, no desenvolvimento dos serviços de saúde e no bem estar da sociedade. Neste artigo, destaca-se a participação recente do IPQ em dois desses projetos, na área das grandezas elétricas, MEMQuD e True8Digit, focando, respetivamente, o desenvolvimento de um novo padrão quântico de resistência elétrica, baseado em dispositivos do tipo memristors e de novas arquiteturas de dispositivos de conversão analógico-digital (ADC) que permita dar um salto significativo na exatidão destes dispositivos na amostragem digital de sinais elétricos (“digitiser”).

Vitor Cabral has received a university degree on Physics Engineering from the Faculty of Sciences and Technology – University of Coimbra – Portugal. He is currently Technical Responsible for the Electricity Laboratory of the Instituto Português da Qualidade (IPQ) – Portugal. His research interests are in the areas of metrology, nanotechnology and quality management systems applied to Laboratory activities.
Luís Ribeiro is a graduate of the Electrical Engineering course at Instituto Superior Técnico – University of Lisbon – Portugal and was part of the Electricity Laboratory of the Instituto Português da Qualidade (IPQ) – Portugal staff between 2009 and 2025, assuming responsibility for the metrological domains of direct and alternating voltage and current, as well as acceleration and vibrations.
Carlos Pires has graduated in Physical Engineering from the Faculty of Sciences of the University of Lisbon and, by the same university, he did a master’s degree in Physical Engineering. In 2007, he started his duties at the Speed Laboratory of the National Metrology Laboratory, of the Portuguese Institute for Quality. In 2015, assumes the functions of head for the Time and Frequency domain. He currently serves as Chair of the Time and Frequency Technical Committee (TC-TF) of EURAMET
Isabel Godinho has a degree in Physics from the Faculty of Sciences of the University of Lisbon and a PhD in Physics from the same University. She is presently Director of the Metrology Department of IPQ and responsible for the national metrology system, in scientific, applied and legal metrology. She is currently EURAMET delegate and European Partnership on Metrology representative and national representative on the OIML and BIPM. Her research interest is in metrology, mainly in the fields of electrical, quantum metrology and acceleration.
