Abstract
Within the field of biosignal acquisition and processing, there is a growing need for combining multiple modalities. Clinical psychology is an area where this is often the case, and one example are the studies where heart rate and electrodermal activity need to be acquired simultaneously. Both of these parameters are typically measured in distinct anatomical regions (the former at the chest, and the later at the hand level), which raises wearability issues as in some cases two independent devices are used; finger clip sensors already enable heart rate measurement at the hand level, however they can be limiting for free living and quality of life activities. In this paper we perform a study and evaluation of an experimental blood volume pulse sensor, to assess the feasibility of measuring the heart rate at the hand palms, and thus enabling the design of more convenient systems for multimodal data acquisition.
