3D-Printed Electrocardiogram Dry Electrodes Using Four Commercially Available Polylactic Acid Conductive Filaments

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Therefore, ability to monitor electrocardiogram (ECG) in long term could save patients’ lives by allowing early diagnosis and intervention. Dry electrodes best option accomplish this task. 3D printing is one popular techniques currently used construct dry electrodes. This project designs, builds, tests, compares printed ECG using four commercially available electrically conductive polylactic acid-based fuzed deposition modeling filaments. Also, uses these acquire raw signals. Then it signals calculating their signal-to-noise ratio (SNR) measure heart rate Pan–Tompkins algorithm. resistance measured. In conclusion, all experiment show acceptable efficiency with SNR values equal or larger than 18.89 dB, prove However, according results experiment, brand (Proto-Pasta) more favorable use. Proto-Pasta has highest value (20.71 dB), second lower (∼ from 600 Ω 2 kΩ), lowest 60 Hz powerline low-frequency noise, most accurate (the have less shape deformity compared other brands), no any noticeable physical malfunction (no knops break during test process).
