Abstract
Medical device design has traditionally prioritized technical performance, reliability, and regulatory compliance. However, many design frameworks give limited attention to human and contextual factors that affect real-world clinical use. This limitation is evident in diagnostic devices that rely on single-mode electrical sensing, such as electrocardiogram (ECG) systems, which can be affected by motion artifacts, electrode misplacement, and signal noise, leading to interpretation errors. We aim to address these limitations by integrating multimodal sensors that combine electrical and mechanical cardiac signals. Here we describe a novel multi-modal measurement strategy for a low-cost ECG system and demonstrate proof of concept using off-the-shelf electronic components. Multimodal sensing can potentially improve signal interpretation, reduce errors, and enhance diagnostic reliability outside of a well-regulated clinical environment.
