Wearable sensors can be worn in several positions, the chest being one of the most effective. In this paper, we have studied the performance of a new piezoresistive breathing sensing system to be worn on the chest with a belt. One of the main problems of belt-attached sensing systems is that they present trends in measurements due to subject movements or differences in subject constitution. These trends affect sensor performance. To mitigate them, it is possible to post-process the data to remove trends in measurements, but relevant data from the respiration signal may be lost. In this study, two different detrending methods are applied to respiration signals. After conducting an experimental study with 21 subjects who breathed in different positions with a chest piezoresistive sensor attached to a belt, detrending method 2 proved to be better at improving the quality of respiration signals. 000123899 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000123899 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000123899 700__ $$0(orcid)0000-0002-1561-0536$$aIgual, Raúl$$uUniversidad de Zaragoza 000123899 700__ $$0(orcid)0000-0001-7550-6688$$aPlaza, Inmaculada$$uUniversidad de Zaragoza 000123899 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
