出汗水平监测能够实现多种应用，例如身体状况估计、个人舒适度监测、健康/运动监测以及对使用者的环境状况的推断。以前的汗液(汗液)传感工作需要用户手动握持设备或将粘合剂传感器直接连接到他们的皮肤上，限制了用户的机动性和舒适性。在本文中，我们提出了一种低成本的新型可穿戴传感器系统，该系统能够根据测量的水分准确地估计个人的汗液水平。传感器设计成线状，可以缝在衣服的接缝里，而不是必须作为一个独立的传感器，用户必须将其连接到自己的身体上。该系统由多根棉包的导电线组成，编织成一个传感器。当一个人出汗时，编织的导电线之间的电阻会随着水分被困在线上的棉花覆盖物中而改变。编织的三维结构允许在可能导致传感器失真的外力(例如运动)存在的情况下稳健地估计出汗水平。我们描述了汗量和编织线之间测量的阻力之间的关系。最后，我们将传感器编织到衬衫的面料上，并进行身体实验，以研究用户在各种活动中的出汗水平。
Perspiration level monitoring enables numerous applications such as physical condition estimation, personal comfort monitoring, health/exercise monitoring, and inference of environmental conditions of the user. Prior works on perspiration (sweat) sensing require users to manually hold a device or attach adhesive sensors directly onto their skin, limiting user mobility and comfort. In this paper, we present a low-cost and novel wearable sensor system that is able to accurately estimate an individual's sweat level based on measuring moisture. The sensor is designed in a threadlike form factor, allowing it to be sewn into the seams of clothing, rather than having to act as a standalone sensor that the user must attach to their body. The system is comprised of multiple cotton-covered conductive threads that are braided into one sensor. When a person sweats, the resistance between the braided conductive threads changes as moisture becomes trapped in the cotton covering of the threads. The braided three-dimensional structure allows for robust estimation of perspiration level in the presence of external forces that may cause sensor distortion, such as motion. We characterize the relationship between the volume of sweat and measured resistance between the braided threads. Finally, we weave our sensors into the fabric of a shirt and conduct on-body experiments to study users' sweating level through various activities.
