Respiratory monitoring is essential in sleep studies, sport training, patient monitoring, or health at work, among other applications. This paper presents a comprehensive systematic review of respiration sensing systems. After several systematic searches in scientific repositories, the 198 most relevant papers in this field were analyzed in detail. Different items were examined: sensing technique and sensor, respiration parameter, sensor location and size, general system setup, communication protocol, processing station, energy autonomy and power consumption, sensor validation, processing algorithm, performance evaluation, and analysis software. As a result, several trends and the remaining research challenges of respiration sensors were identified. Long-term evaluations and usability tests should be performed. Researchers designed custom experiments to validate the sensing systems, making it difficult to compare results. Therefore, another challenge is to have a common validation framework to fairly compare sensor performance. The implementation of energy-saving strategies, the incorporation of energy harvesting techniques, the calculation of volume parameters of breathing, or the effective integration of respiration sensors into clothing are other remaining research efforts. Addressing these and other challenges outlined in the paper is a required step to obtain a feasible, robust, affordable, and unobtrusive respiration sensing system.
呼吸监测在睡眠研究、运动训练、患者监测或工作场所健康等应用中至关重要。本文对呼吸传感系统进行了全面的系统综述。在科学资源库中进行了几次系统搜索后，详细分析了该领域中 198 篇最相关的论文。检查了不同的项目：传感技术和传感器、呼吸参数、传感器位置和大小、一般系统设置、通信协议、处理站、能源自主和功耗、传感器验证、处理算法、性能评估和分析软件。结果确定了呼吸传感器的一些趋势和剩余的研究挑战。应进行长期评估和可用性测试。研究人员设计了定制实验来验证传感系统，这使得比较结果变得困难。因此，另一个挑战是拥有一个通用的验证框架来公平地比较传感器性能。节能策略的实施、能量收集技术的纳入、呼吸体积参数的计算，或呼吸传感器有效地集成到服装中，都是其他剩余的研究工作。解决本文中概述的这些和其他挑战是获得可行、稳健、经济实惠和不引人注目的呼吸传感系统的必要步骤。
