Contextual measurements of multiple physiological signals using familiar garments or accessories can provide insights into health and behavior. Recording these signals on or near the face is challenging because most subjects are sensitive to implements placed on the face or head. Here, fabric electrodes and garment design strategies are used synergistically to afford an unobtrusive platform, Chesma, for longitudinal acquisition of physiological signals from a user's face. Chesma contains two novel fabric-based electrodes: a hydrogel electrode (tAgTrode) that retains its ionic character after multiple uses/washes, does not cause skin irritation, and can be continuously operated for upward of 8 h without losing signal integrity. Second is an ion-conductive fabric pressure sensor (Press-ION) that captures pulse waveforms. When sewn onto a lightweight eye mask, these electrodes simultaneously gather complementary electro-oculography and cardiac data, which can enable sleep quality and psychological studies and improve the accuracy and usability of virtual reality headsets.

使用熟悉的服装或配饰对多种生理信号进行上下文测量可以洞察健康和行为。在大多数情况下，将这些信号记录在脸部或附近非常困难，因为大多数对象对放置在脸部或头部的工具都很敏感。在这里，织物电极和服装设计策略可以协同使用，以提供一个不引人注目的平台Chesma，以便从用户面部纵向采集生理信号。Chesma包含两个基于织物的新型电极：水凝胶电极（tAgTrode），在多次使用/清洗后仍保持其离子特性，不会引起皮肤刺激，并且可以连续工作8小时以上而不会丢失信号完整性。第二个是离子导电织物压力传感器（Press-ION），用于捕获脉冲波形。
