Un banc dʼessai à multi-capteurs pour la détermination du débit dʼabsorption spécifique (DAS) dans le cas dʼéquipements sans fil émettant dans des tissus analogues à ceux du corps humain est présenté. Une estimation en temps réel des taux dʼabsorption spécifique est proposé, considerant un banc dʼessai à multi-capteurs distribués spatialement. En comparaison dʼun système comportant un robot multi-axial pour la mesure des DAS, celui qui est proposée ici ne requiert aucun déplacement, reduisant ainsi de manière drastique le temps dʼacquisition, dès lors que des techniques parallèles dʼacquisition de données et dʼinterpolation sont employées afin dʼaccélérer les mesures.
A multi-sensor test-bench for determining the SAR (specific absorption rate) due to wireless devices emitting in equivalent human tissues is presented. Real-time SAR assessment is proposed considering a spatially distributed multiprobe test-bench. In comparison with a multi-axial robot SAR system, the proposed one does not require any displacement, thus reducing drastically acquisition time, once parallel data acquisition and interpolation techniques are employed for accelerating measurements.
