Flexible Copper Tape based ECG Electrodes

Through conformal integration across the target surface, flexible electronics a rapidly developing field of technology—offers safe, pleasant, and non-intrusive solutions to overcome challenges in recording and monitoring various bio-signals. This has the potential to change healthcare. Polymers are frequently utilized as substrates to create flexible electrodes, particularly when those electrodes need to be biocompatible and conformally bonded to the underlying substrate. Electrodes are the most common type of flexible electronic structure among these devices that are used to record bioelectric signals. Their potential uses are numerous and include monitoring physiological signals like ECG, EEG, and EMG, developing sensors for parameters like glucose levels, pH, and lactic acid, and even electrically stimulating muscles, nerves and wounds. In the present work, aluminum thin film over PDMS and Kapton tape along with readily available copper tapes were explored for electrode development. While electrodes over PDMS developed cracks and those over Kapton tape had conformality issues, proper ECG signals were received over copper tape electrodes in combination with conventional electrodes. To determine the effectiveness of this study and any prospective benefits in the areas of flexible electronics and bioelectric signal capture, the results were also compared with those from traditional electrodes.
