As Empatica E4 EDA/GSR wristband is discontinued, we are looking for a new device that can be used for scientific research. Ideally, a wristband and no electrodes since we would like to use it in the real world executing mobility tasks. Is there a compact sensor that could maybe measure HR, HRV, or provide EEG and VR integration possibilities? I am aware of Shimmer and EmbracePlus, looking forward to hearing about your experience with those or recommendations on other devices.
