Continuous monitoring of vital bio-signals is crucial to track the well-being of patients and to allow for timelymedical intervention in cases of emergency. This paper presents a compact and wearable electrocardiogram (ECG) sensor using graphene-elastomer electrodes, which were characterised, first using an electronic patient simulator, then on a human subject. We demonstrate that the proposed electrodes are highly conductive, flexible and ultralight (weighing less than 10 mg). Their skin-impedance values are significantly lower than existing electrodes including other graphene-based sensors. In addition, we demonstrate that they can be applied on the skin in dry form without needing an inte..View full abstract
