Researchers at the University of California, San Diego have developed a pair of earbuds that can record the electrical activity of the brain and levels of lactate in the body. The breakthrough technology involves two flexible sensors screen-printed onto a stamp-like flexible surface that are attached to the earbuds. The sensors can communicate with the earbuds to wirelessly transmit the collected data for visualization and analysis on a smartphone or laptop. The data gathered from these biosensors can be used for health monitoring and diagnosis of neuro-degenerative conditions. The sensors are less cumbersome than current devices used for brain activity and sweat secretion sensing and can be used in the real world during exercise. The research team believes that this technology could lead to advancements in health and wellness monitoring using wearable devices such as earbuds, watches, and more.
