## 3 Conclusions  
This Special Issue aims to contribute to the exploration of significant advancements in sensor and measurement system technologies. Through a brief overview of the selected research papers, this editorial highlights the innovative approaches and potential impacts of sensor-driven solutions in addressing the challenges faced by the maritime sector. The articles presented in this Special Issue provide valuable insights into the implications for future research in the maritime industry, which can be summarized as follows. The transformative impact of sensor technologies on maritime engineering is underscored by the convergence of innovation, interdisciplinary collaboration, and the continuous pursuit of safety, efficiency, robustness, and low costs. For instance, additive manufacturing has emerged as a potential enabler that offers flexibility, speed, cost-effectiveness, and adaptability to diverse operational environments for sensor fabrication; the work by [PERSON] et al. illustrates this paradigm shift, showcasing the seamless integration of additive manufacturing and standard airfoil geometry in the design of mass airflow sensors for marine engineering applications. In addition, the development of micro-pressure sensors tailored to harsh environments by [PERSON] et al. showed the need for robust sensor technologies in marine applications; most probably, future research will explore the integration of advanced materials to improve sensor performance and longevity in challenging marine conditions. Furthermore, the selected research papers highlighted the multifaceted roles of sensor/measurement system technologies in enhancing safety, efficiency, and predictive capabilities across various maritime domains. From the development of rotational-linear triboelectric nanogenetators by [PERSON] et al., offering renewable energy solutions for maritime applications, to the advanced monitoring of offshore steel pipelines by [PERSON] et al., leveraging wireless communication and aerial photography to mitigate transportation risks, each study underscores the transformative potential of sensor-driven solutions. Additionally, the deployment of novel analytic techniques, as demonstrated by [PERSON] et al., [PERSON], and [PERSON], empowers maritime stakeholders with predictive insights, real-time diagnostic capabilities, and better productivity prediction, thereby optimizing resource utilization and mitigating operational risks. Future research could explore the application of advanced radar technologies for precise ocean current measurements, aiding climate studies and maritime navigation in dynamic ocean environments, the potential of non-intrusive diagnostic measurements for quick and less resource-intensive identification of engine malfunctions (e.g., employing engine Instantaneous Crankshaft Torque), and de-risking hydrocarbon exploration in deep marine environments by accurately predicting hydrocarbon depths, leading to more cost-effective exploration campaigns. The future trajectory of sensor technologies in the maritime industry is promising, focusing on novel sensors and measuring systems that can enhance safety, efficiency, sustainability, and technological advancements to meet the continuously evolving needs of marine applications. Thus, the current studies presented in this Special Issue should be seen not only as the research results of investigations carried out by the respective researchers but also as key starting points, inviting readers to continue with new studies on the themes explored. In light of the aforementioned considerations, it is the editor's belief that future marine sensing devices will increasingly incorporate advances from other scientific disciplines, revolutionizing their manufacturing and operation, similar to the miniaturization that occurred due to the vast advances in the semiconductor industry in the past.
