“…This was the most common trend by far. It was also common that sensors were embedded in shirts at chest or abdomen level [ 21 , 49 , 59 , 65 , 69 , 84 , 85 , 94 , 108 , 113 , 123 , 142 , 143 , 151 , 235 ]. This was the location selected by 15% of the studies.…”

“…Twenty-six studies reported that motion artifacts were considered during testing. They showed that the inclusion of motion artifacts in experiments greatly influenced sensor performance [ 2 , 9 , 17 , 53 , 61 , 62 , 66 , 67 , 68 , 81 , 108 , 109 , 117 , 119 , 131 , 132 , 135 , 147 , 157 , 178 , 187 , 190 , 196 , 205 , 210 , 221 , 225 ]. In relation to the activities or positions considered in the experiments, lying down and sitting were the most tested positions.…”

“…In relation to the activities or positions considered in the experiments, lying down and sitting were the most tested positions. Other positions or activities, like standing, walking, moving, or running, were used in a minority of studies [ 2 , 17 , 21 , 61 , 62 , 66 , 67 , 68 , 77 , 79 , 81 , 91 , 94 , 101 , 102 , 103 , 108 , 110 , 111 , 115 , 118 , 119 , 124 , 129 , 131 , 132 , 135 , 146 , 147 , 148 , 149 , 177 , 178 , 188 , 205 , 214 , 233 , 235 ].

“…Other parameters, such as size or weight, can also affect the adoption of the technology. These parameters have only been provided in a limited number of studies [ 2 , 3 , 17 , 21 , 49 , 62 , 64 , 68 , 72 , 85 , 93 , 94 , 97 , 98 , 99 , 103 , 105 , 108 , 110 , 113 , 114 , 116 , 119 , 120 , 124 , 126 , 135 , 136 , 138 , 141 , 143 , 144 , 146 , 148 , 161 ]. Future works should also consider size and weight as important factors in the design of sensing systems, subjecting them to evaluation.…”

“…This framework should include quiet and rapid breathing and different postures, such as standing, lying, or sitting. Experiments should include motion artifacts since they affect sensor performance, as shown by several studies [ 53 , 108 , 157 , 158 ]. Additionally, they should involve a number of users high enough to obtain significant results.…”

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.

Developing an unobtrusive respiration sensor is a key task for daily health and safety monitoring, especially for individuals with potential breathing abnormalities or those performing in physically challenging conditions. This study introduces a machine‐embroidered enclosure that guides a soft and extensible lightguide to react to the strains on a compression shirt caused by the respiration of the wearer. The shape of the stretchable optical fiber changes from serpentine in rest (exhalation) to straight under strain (inhalation), which affects the light transmittance. In tests with 13 healthy adults, the respiratory volume prediction through a deep learning model trained by the light intensity and truth from a commercial spirometer shows a high correlation in both static (r2 > 0.880) and dynamic postures (r2 > 0.690). This system also accurately measures the respiratory rate under sitting and walking conditions (absolute error <1.513 BPM, SNR > 7.122 dB). The strain‐sensing capability of this sensor depends on the parameters of the embroidery, including the stitch density, stitch tightness, and embroidery shape. Durability tests confirm that the system still functions after 100 000 abrasions and 10 cold washes.
