Screen-Printed, Flexible Sensors Transform Earbuds into Exercise-, Brain-Activity-Level Recording Device

A pair of earbuds can be turned into a tool to record the electrical activity of the brain as well as levels of lactate in the body with the addition of two flexible sensors screen-printed onto a stamp-like flexible surface. While in-ear sensing of several physiological parameters is not new, integrating sensing of brain and body signals in a single platform is. Watch this video to learn more about the technology, which was developed at the University of California San Diego.

"Being able to measure the dynamics of both brain cognitive activity and body metabolic state in one in-ear integrated device that doesn't intrude on the comfort and mobility of the user opens up tremendous opportunities for advancing health and wellness of people of all ages, anytime and anywhere,” said Gert Cauwenberghs  , a professor in the Shu Chien Gene Lay Department of Bioengineering at UC San Diego.

    00:00:00 these screen printed flexible sensors designed by researchers from the jacobskov engineering at UC San Diego allow earbuds to record brain activity and exercise levels it's the first time that one single platform brings together the sensing of brain and body signals inside the human ear the earbuds transmit wirelessly the data

    00:00:21 gathered by the sensors to either a smartphone or a laptop so that it can be visualized and analyzed the data can be used for long-term Health monitoring and also to detect long-term neurodegenerative conditions for example data from an electron encephalogram or EEG and data from lactate and sweats can be combined to diagnose different kinds of seizures

    00:00:44 including epileptic seizures next steps include processing the data on the device itself and Gathering more data such as glucose levels [Music]
