The Galvanic Skin Response (GSR) signal, measured as the electrical conductance between a pair of electrodes placed over a person’s skin, consists of a tonic component superposed by a phasic component. In the GSR phasic component several peaks appear corresponding to specific events. Therefore, the information content of peaks is very useful in a wide range of applications. This work investigates the effectiveness of a decomposition-based Compressed Sensing (CS) approach for extraction of peaks from GSR signals acquired with an IoT-enabled wrist-worn device, during unpleasant sound stimulation. Then, once the sparse peaks are detected, the overall GSR phasic component is reconstructed, too.

Abstract
The Galvanic Skin Response (GSR) signal, measured as the electrical conductance between a pair of electrodes placed over a person’s skin, consists of a tonic component superposed by a phasic component. In the GSR phasic component several peaks appear corresponding to specific events. Therefore, the information content of peaks is very useful in a wide range of applications. This work investigates the effectiveness of a decomposition-based Compressed Sensing (CS) approach for extraction of peaks from GSR signals acquired with an IoT-enabled wrist-worn device, during unpleasant sound stimulation. Then, once the sparse peaks are detected, the overall GSR phasic component is reconstructed, too.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
