A therapeutic glove, which enables medical non-professionals to perform physiotherapeutic gripping and holding movements on patients, would significantly improve the healthcare situation in physiotherapy. The glove aims to detect the orthogonal pressure load and provide feedback to the user. The use of textile materials for the glove assures comfort and a good fit for the user. This, in turn, implies a textile realization of the sensor system in order to manufacture both the glove and the sensor system in as few process steps as possible, using only one textile manufacturing technique. The flat knitting technology is an obvious choice here. The aim of the study is to develop a textile capacitive pressure sensor that can be integrated into the fingertips of a glove using flat knitting technology and to evaluate its sensor properties with regard to transmission behavior, hysteresis and drift. It was shown that the proposed method of a flat knitting sensor fabrication is suitable for producing both the sensors and the glove in one single process step. In addition, the implementation of an entire glove with integrated pressure sensors, including the necessary electrical connection of the sensor electrodes via knitted conductive paths in three fingers, was successfully demonstrated.
一种治疗手套能够让医学非专业人员对患者进行物理治疗中的抓握动作，这将显著改善物理治疗中的医疗状况。该手套旨在检测正交压力负荷并向用户提供反馈。使用纺织材料制作手套可确保用户佩戴舒适且贴合。这进而意味着要以纺织方式实现传感器系统，以便仅使用一种纺织制造技术，尽可能少的工艺步骤来制造手套和传感器系统。横机编织技术在此是个显而易见的选择。本研究的目的是开发一种可通过横机编织技术集成到手套指尖的纺织电容式压力传感器，并评估其在传输行为、滞后和漂移方面的传感器特性。结果表明，所提出的横机编织传感器制造方法适用于在单个工艺步骤中生产传感器和手套。此外，还成功展示了一款集成压力传感器的完整手套的制作，包括通过三个手指中的针织导电路径对传感器电极进行必要的电气连接。
