The collection includes three distinct devices: OpenEarable 2.0, OpenEarable ExG, and OpenEarable ExG Headphones. "OpenEarable 2.0" integrates advanced sensors, such as ultrasound-capable microphones, a 9-axis inertial measurement unit, a pulse oximeter, an optical temperature sensor, and an ear canal pressure sensor, enabling extensive health monitoring, activity tracking, and human-computer interaction. "OpenEarable ExG" is an open-source platform focused on measuring biopotentials like EEG, ECG, and EMG, using up to four sensing channels, and validated for detecting eye movements, brain activity, and muscle contractions. "OpenEarable ExG Headphones" combine electrophysiological sensing with high-quality audio, utilizing OpenBCI biosignal amplification and a 3D-printed over-ear design for reliable EEG, EOG, ECG, and EMG measurements. The OpenEarable Suite aims to democratize earable research by providing accessible, open-source tools in different form factors that follow best practices in hardware and software development, facilitating diverse applications across various domains from medical to HCI.enhttp://purl.org/eprint/accessRights/RestrictedAccessearableshearablesopen-source hardwareOSHWopen wearablesText/Conference Paper10.18420/muc2024-mci-demo-317
