The Shimmer 3 is a portable device to collect physiological data. The lab has two Shimmer 3 kits that can each capture different data: the GSR+ kit and the ECG/EMG Unit kit.
The GSR+ kit is mainly used for arousal and stress measures, for example to study implicit responses to stimuli (e.g. text, movies, advertisement, …). It includes two sensors:
- GSR: to measure skin conductance
- PPG: to measure heart rate variability through blood volume pulse
The ECG/EMG Unit kit also has two sensors:
- ECG: to measure muscle activity/tension
- EMG: to directly measure heart rate
In contrast to the GSR+ kit, these sensors cannot be used simultaneously. The ECG/EMG Unit kit can be used for arousal, heart rate, muscle, gait, and posture data analysis. It can be used to study, for example, physical approach behaviour and to triangulate GSR data.
The Shimmer 3 sensors is used together with the iMotions software package.
