Abstract: The present invention relates to a wearable sensor device and method for a thermogenic and/or psychogenic stress response of a subject. The wearable sensor device comprises a first electrode (11) configured to contact a first non-glabrous skin part of the subject, a second electrode (12) configured to contact a second non-glabrous skin part of the subject, a third electrode (13) configured to contact a glabrous skin part of the subject, and a skin conductance sensor (14) configured to provide a voltage signal between a positive input terminal (141) and a negative input terminal (142) and to measure a skin conductance signal at an output terminal (143). A switching arrangement (15) switches connections between the first to third electrodes and the positive and negative input terminals of the skin conductance sensor between at least three switching states.
