Sommario
On Friday, October 24, 2025, at 11:30 am we will have a new talk for the series #NECSTFridayTalk.During this talk, we will have, as speaker, Susanna Bardini, PhD at Dipartimento di Elettronica, Informazione e Bioingegneria.
Sleep is vital for overall health, cognitive function, and well-being. However, traditional methods like polysomnography are expensive and impractical for continuous use. To address this challenge, we present OptoSens, a non-invasive wearable system that uses optical sensors to track eye movements and classify sleep stages, such as REM, light sleep, deep sleep, and wakefulness. Designed for everyday use, OptoSens is a lightweight and affordable alternative to traditional sleep monitoring, offering useful insights into sleep quality without discomfort. Building on wearable technology, Morpheus takes the next step by integrating commercially available wearables with environmental factors like temperature, humidity, and noise. This combination helps optimize sleep quality by offering real-time, personalized recommendations to improve the sleep environment. By merging well-established sleep tracking technologies with environmental data, Morpheus demonstrates the value of considering multiple factors in sleep optimization. Lastly, IGEA builds upon this work, using federated learning to predict sleep quality by combining wearable data with local environmental inputs. This approach ensures data privacy by processing information locally, without the need for centralized storage. IGEA offers a scalable, decentralized solution for personalized sleep monitoring, making it suitable for a range of smart environments, from university dormitories to smart homes. Together, these systems highlight the evolution from wearable-based tracking to integrating environmental factors, ultimately advancing toward a privacy-focused, scalable solution for improving sleep quality and overall well-being.
The NECSTLab is a DEIB laboratory, with different research lines on advanced topics in computing systems: from architectural characteristics, to hardware-software codesign methodologies, to security and dependability issues of complex system architectures.
Every week, the “NECSTFridayTalk” invites researchers, professionals or entrepreneurs to share their work experiences and projects they are implementing in the “Computing Systems”.
