Earbud biosensors
Simultaneous sensing Flexible electrochemical and electrophysiological sensors are attached to in-ear headphones, or earbuds, via a stamp-like surface. Once the earbuds are inserted in the ear canal, the sensors simultaneously monitor brain states and exercise levels. (Courtesy: Erik Jepsen/University of California San Diego)
Earbuds equipped with biosensors can continuously measure the electrical activity of the brain and l
