在过去的十年中，可穿戴技术一直在迅速增长。最发达的应用之一是使用基于纺织品的传感器和电极进行生理和医学评估。整合到此类系统中的传感器有望在日常生活中支持对个人活动的监视，并确保早期发现异常状况（例如睡眠呼吸暂停），这是一种睡眠障碍现象。结合服装编织是一步过程，是一个步骤，这使得在编织过程中直接将基于纺织品的传感器集成到衣服中。该项目的目的是设计一个具有不同导电纱线和结构的纬线针织拉伸传感器。通过测量针织结构的电阻变化，通过自行循环测试仪的伸长函数来评估传感器的性能。此外，为了评估传感器性能作为呼吸率指示器，已经制作了扁平编织机制作的原型服装。
Wearable technologies have been rapidly growing during the last decade. One of the most developed applications is the physiological and medical evaluation by using textile based sensors and electrodes. Sensors integrated into such a system are expected to be able to support the monitoring of personal activity during daily life and ensure the early detection of abnormal conditions such as sleep apnea which is a sleeping disorder phenomenon .Complete garment knitting is a one-step process, which enables to integrate the textile based sensor into a garment directly in the knitting process. The objective with this project was to design a weft knitted stretch sensor of different conductive yarns and structures. The performance of the sensors was evaluated by measuring the electrical resistance changes in the knitted structure as a function of elongation with a self-built cyclic tester. In addition, a prototype garment made by flat knitting machine has been made in order to evaluate the sensor performance as a breathing rate indicator.
