What is it about?

BUZZ-PR is a wearable neuroadaptive system that monitors astronaut stress via EEG and PPG, using student-made software personalized to each individual to deliver non-invasive brain stimulation (tDCS) and enhance cognitive resilience during long missions.

Why is it important?

BUZZ-PR is important because it integrates biosensing (EEG/PPG) with personalized neuromodulation (tDCS), enabling early detection and intervention for stress and fatigue. This preserves astronaut cognitive function, mental health, and mission safety during long-duration spaceflight.

Perspectives

When I worked on the BUZZ-PR paper, I realized how ambitious this project was and how much it could contribute. For me, the most important part was proving that a group of students from different disciplines could create something real and meaningful to address a critical challenge in space exploration: astronaut mental and cognitive health. What motivated me most is that BUZZ-PR is not a reactive solution like medication, but a proactive system that detects stress in real time and provides personalized support. I feel this approach opens the door to a new way of thinking about space medicine. On a personal level, I’m proud that, as students, we were able to design not just the concept, but also the system architecture, safety protocols, and testing plans. For me, BUZZ-PR is not only an academic project, but also an early step toward technologies that can transform how we care for the human mind in space—and here on Earth as well.
