感测身体中的水肿或肿胀是可穿戴技术的许多临床和美容应用的感兴趣的参数。水肿会提高对压力点的敏感性，这使得基于软织物的传感器特别有吸引力。然而，肿胀会引起身体周长的缓慢、渐进的变化，这可能难以准确地感知，特别是使用柔软的电子纺织品传感器。人体测量变异性、传感器放置和身体运动进一步混淆了准确性。在这里，我们探讨了准确地感知踝关节肿胀的可行性，通过一组传感器的比较评估代表3软测量机制在三个频率条件下的线性应变台架测试。然后将这些传感器应用于模拟膨胀实验中，以评估其相对于与膨胀中经历的那些类似的周向变化的性能。我们发现，两个传感器（缝合和电容）表现出可靠的性能，接近或超过专家人类测量肿胀。电阻聚合物线和电容传感器在中高频扩展下表现出准确的响应。
Sensing edema or swelling in the body is a parameter of interest for many clinical and cosmetic applications of wearable technology. Edema creates heightened sensitivity to pressure points, making soft textile-based sensors particularly attractive. However, swelling induces slow, gradual changes in body circumferences, which can be difficult to sense accurately, especially with soft e-textile sensors. Anthropometric variability, sensor placement, and body movements further confound accuracy. Here, we explore the feasibility of accurately sensing ankle swelling through a comparative assessment of a set of sensors representing 3 soft sensing mechanisms in a linear-strain bench test under three frequency conditions. These sensors are then applied in a simulated swelling experiment to assess their performance relative to circumferential changes similar to those experienced in swelling. We find that two sensors (stitched and capacitive) demonstrate reliable performance that approximates or exceeds expert human measurement for swelling. Resistive polymer cord and capacitive sensors exhibited accurate response under medium- and high-frequency extensions.
