In-ear integrated EEG sensor for continuous brain activity and metabolic monitoring A recent study published in Nature Portfolio by Yuchen Xu and colleagues introduces an in-ear sensor array that continuously monitors brain activity and lactate levels in sweat, marking a significant advancement in non-intrusive health monitoring solutions. This sensor array, placed on a flexible substrate around a user-generic earphone, utilizes the ear's exocrine sweat glands to measure lactate concentration. It also monitors brain states through electroencephalography, electrooculography, and electrodermal activity. During exercise, the device detected elevated lactate levels in sweat concurrently with the modulation of brain activity across all EEG frequency bands. This innovative approach enhances our understanding of the dynamic interactions between brain and body biomarkers, potentially leading to breakthroughs in long-term health monitoring and the management of neurodegenerative diseases such as #Epilepsy. 👇🏻 Read more in the full article linked in the comment section. #MedicalDevices #Biomarker
