Flexible transdermal patch for EEG and ECG monitoring

    Flexible electronics is growing rapidly. As Medgadgets learned, the Illinois Institute has developed a flexible patch for monitoring EEG (electroencephalogram, electrical brain activity) and ECG (electrocardiogram, recording electrical heart signals). The corresponding press release on the launch of the first prototypes was posted on the website of the institution.




    The Illinois University website recently published a press release on a flexible patch for EEG and ECG monitoring. The first prototypes of flexible devices that fit on the skin and provide continuous health monitoring have been demonstrated in the past by employees of the University of Illinois under the leadership of John Rogers.

    Unlike early experiences in developing flexible devices, the technology required the development of individual components from scratch. This process seemed complicated, because the new components were not easy to make as flexible and efficient as the original ones. As a result of the work carried out, the same group of developers, in collaboration with a team from Northwestern University, integrated standard microcircuits into flexible electronic patches to conduct high-quality ECG and EEG monitoring.



    Since the patch contained hard parts on its surface, the development team modified it using microfluidic technologies, which were supposed to be very flexible, soft and contain liquid. The wires connecting the microcircuit to other parts of the patch are flexible in all directions, which allows the patch to be worn on virtually any part of the body. In fact, the patch receives wireless power and transmits a signal of data that is collected and displayed on an external device, for example, on a smartphone. The creators of this new technology tested and compared the patch with commercially available ECG and EEG devices and found that it "functioned just like conventional sensors, but, unlike them, was much more convenient for patients."
