Article Title: Balancing Between Privacy and Utility for Affect Recognition Using Multitask Learning in Differential Privacy–Added Federated Learning Settings: Quantitative Study
Article Snippet: In the WESAD dataset, each participant recorded physiological signals such as blood volume pulse, electrocardiogram (ECG), EDA, electromyogram, respiration, body temperature, and 3-axis acceleration measured from the chest and wrist using Plux RespiBAN and Empatica E4 devices.

Article Title: A PPG Signal Dataset Collected in Semi-Naturalistic Settings Using Galaxy Watch
Article Snippet: To address this gap, this study presents GalaxyPPG, a dataset collected from 24 participants that includes wrist-worn PPG signals from a Galaxy Watch 5 and an Empatica E4, alongside chest-worn ECG data from a Polar H10.

Article Title: EEG and Physiological Signals Dataset from Participants during Traditional and Partially Immersive Learning Experiences in Humanities
Article Snippet: • Data format: – Physiological data from OpenBCI and Empatica E4 devices were recorded and organized into five files: one resting state file consisting of physiological signals of the participants and four files recorded during users’ experiences during each of the scenes.

Article Title: MSPTDfast: An Efficient Photoplethysmography Beat Detection Algorithm
Article Snippet: The data consisted of wrist PPG signals acquired using an Empatica E4 device, alongside simultaneous ECG signals from which reference heartbeat timings were obtained.

Article Title: Integrating Biofeedback and Artificial Intelligence into eXtended Reality Training Scenarios: A Systematic Literature Review
Article Snippet: Also, Wilson et al. (2021) observed that many applications can get “good-enough” results using only the sensors from the Empatica E4 wrist-band.
