可穿戴技术正在获得动力和广泛传播。由于有了活动跟踪器等设备，最终用户越来越了解他们的日常活动，姿势和训练，并可以修改他们的运动行为。活动跟踪器优选地基于惯性传感器，诸如加速度计和陀螺仪。我们承受的负荷和它们施加在我们身体上的界面压力也会影响姿势。接触界面压力感测可穿戴设备将有益于补充惯性活动跟踪器。是什么阻止力敏电阻器（FSR）成为下一个最畅销的可穿戴设备？在本文中，我们提供的元素来回答这个问题。我们建立了一个FSR的基础上的导电材料（Velostat）和印刷导电油墨电极上的聚对苯二甲酸乙二醇酯（PET）基板;我们测试其响应的压力范围为0-2.7 kPa。我们提出了一个国家的最先进的审查，过滤的需要，以确定足够的可穿戴设备的技术。我们的结论是，重复性是尚未解决的主要问题。
Wearable technologies are gaining momentum and widespread diffusion. Thanks to devices such as activity trackers, in form of bracelets, watches, or anklets, the end-users are becoming more and more aware of their daily activity routine, posture, and training and canmodify their motor-behavior. Activity trackers are prevalently based on inertial sensors such as accelerometers and gyroscopes. Loads we bear with us and the interface pressure they put on our body also affect posture. A contact interface pressure sensing wearable would be beneficial to complement inertial activity trackers. What is precluding force sensing resistors (FSR) to be the next best seller wearable? In this paper, we provide elements to answer this question. We build an FSR based on resistivematerial (Velostat) and printed conductive ink electrodes on polyethylene terephthalate (PET) substrate; we test its response to pressure in the range 0-2.7 kPa. We present a state-of-the-art review, filtered by the need to identify technologies adequate for wearables. We conclude that the repeatability is the major issue yet unsolved.
