Greco thinks that this non-invasive brainwave monitoring tech might prove a crucial step in helping other researchers around the world develop increasingly more effective non-invasive BMI technologies that one day would be small enough and sensitive enough to be built into everyday smart devices like your smartphone or the ones in your smart connected home. There are other practical use cases, too. “This kind of electrode could be used to monitor the patient at home to help clinicians to understand the origins and how it is propagated. “In the case of epilepsy, you cannot really predict an episode, you need to be able to monitor the patient,” Ismailova explained. Neurological conditions like epilepsy may be diagnosed using EEG technology but it is unlikely patients will have regular, or even irregular, brainwave monitoring afterward. If something goes wrong, the smartwatch can alert the user so that they may seek medical help.Īt present, there is no such thing as regular brainwave monitoring. In the case of the Apple Watch, conditions like atrial fibrillation, an irregular heart rhythm that can cause strokes, can be spotted by continually monitoring wearers’ heartbeat. The Electrocardiogram (ECG) reader found in the Apple Watch has already compellingly demonstrated why wearables that constantly monitor our vital signs can be useful. There are multiple reasons why gathering brain data could be useful. It is very to catch this kind of activity.” “We have now reached the ultimate step where we can brainwaves that are low amplitude and high frequency. “EEG, or electroencephalography, was always the most challenging step,” said Esma Ismailova, bioelectronic textiles group leader in the department of bioelectronics at Ecole Nationale Supérieure des Mines de Saint-Étienne. The work was carried out alongside researchers in both France, at the École des Mines de Saint-Étienne, and in Italy by Laura Ferrari at Scuola Universitaria Superiore Pisa. Half a decade on, Greco and others have optimized the technology so that it can be used to measure brain waves every bit as effectively. The first use case of these adhesive transfers was to measure heart rate and muscle activity. Greco’s lab, the Laboratory of Applied Materials for Printed and Soft electronics (LAMPSe), developed the first tattoo electrodes in 2015. The fact that they could be applied and then forgotten about is one of their most exciting aspects, making them perfectly suited for longer-term measurements, and they stay on until scrubbed with soap and water to remove them.Ī description of the technology breakthrough While the tattoo electrodes are not exactly invisible, anyone shaved bald and sporting a small circuit board glued to their head has a funny habit of being conspicuous, they don’t interfere with the wearer the way that a conventional EEG electrode headset might do.
