A performance testing platform of ECG electrodes based on Millipore films

With the continuous development of wearable health monitoring technology, new types of Electrocardiogram (ECG) electrodes become the focus of attention, such as textile electrode, non-contact electrode, and micro-needle electrode. However, there are not yet unified performance testing methods for different types of electrodes. Two evaluating indicators proposed in the national pharmaceutical industry standard YY/T 0196-2005 (disposable ECG electrodes) are DC offset voltage and AC impedance. In t
