WADEDA: A Wearable Affective Device with On-Chip Signal Processing Capabilities for Measuring ElectroDermal Activity

Abstract

In this paper a miniaturized and wearable skin conductance sensor equipped with a micro-processor is proposed. The device facilitates the acquisition of long-term monitoring of the electrodermal activity under real-world situations. Its generic and flexible design permits the data storage during daily activities, while the prototype equipped with on-chip firmware, performs real-time signal filtering and feature extraction. The system’s architecture based on the recent hardware advances, aims to enhance the robustness of previous skin conductance sensors. Emerging applications under non-laboratory experiments are introduced in order to highlight the applicability of the proposed device. The results obtained from preliminary experiments are described.
