This study examines the evolution of Living Lab (LL) research and practice over the past decade, focusing on the principles guiding their development and their application in addressing contemporary societal, technological, and environmental challenges. Using a case study approach, nine European projects spanning diverse domains such as urban resilience, digital privacy, climate change, and rural digitalization are analysed. The findings reveal significant transformations in LL methodologies, including an increased emphasis on early stakeholder engagement, iterative processes, and value co-creation. Additionally, the integration of advanced technologies such as AI and IoT, coupled with a commitment to social inclusivity and ethical governance, has elevated LLs from experimental innovation spaces to systemic platforms addressing global challenges. This paper highlights key shifts in LL practices, offering insights for enhancing their adaptability and effectiveness.
