| Popis: | [EN] Wireless in-body devices are those in which a medical sensor is introduced-implanted or ingested- inside the human body and communicates with a remote node. Some in-body applications demand high data rates, so ultrawideband (UWB) spectrum has been proposed as a good candidate because of its large bandwidth available. Besides, breathing can lead to internal movement of the torso and consequently, of devices installed in this area. Thus, the radio channel performance can be affected by such movement leading to a malfunction of the radio interface of the medical device. This work aims at analyzing the effect of breathing on the propagation channel by means of in vivo measurements in living animal models. Continuous wave (CW) measurements have been carried out for live different frequencies in the lower part of the UWB band, and the effects of breathing on the relative received power (module and phase) are analyzed and discussed This work was supported in part by the Ministerio de Ciencia e Innovacion under Grant RTI2018-099880-B-C31 and in part by the Vicerrectorado de Investigacion, Innovacion y Transferencia de la Universitat Politecnica de Valencia through the Colorrectal Diagnosis of Tumours Based on EM Properties (COLODEM) Project under Grant PAID-06-18 (First Research Projects) |
