Low-Modulus, Low-Motion-Artifact Sensor for Biological Signal Recording

Here we report a low-modulus, low-motion-artifact (LMLMA) sensor for electrocardiography (ECG) recording. Motion artifacts are one of the most prominent issues of both wet and dry electrophysiological electrodes/sensors. Our soft and stretchable LMLMA sensor shows significantly lower motion artifacts than gold-standard medical grade Ag/ AgCI electrodes This sensor is easy to use, comfortable to wear, waterproof, and fabricated using a low-cost, time-effective, and scalable method. LMLMA sensor is connected to our developed soft and stretchable wearable wireless circuit for long-term mobile ECG recording on personal devices.
