“…Their design featured a conical-shaped earplug made of biocompatible silicone rubber. In recent years, some innovative and effective designs for generic in-ear EEG sensing devices have been proposed [31][32][33][34]. For instance, Kaveh et al [32] used a 3D scan of the in-ear structure to create a unique, generic design that can fit all users.…”

“…In 2022, Paul et al [34] introduced the weDAQ system, a complete wireless electrophysiology data acquisition system that can simultaneously acquire multiple biological data streams, including in-ear EEG. Their weDAQ system features a unique generic design for in-ear EEG sensing, composed of two planar 'crocodile' PCBs that fit together and form a 3D in-ear apparatus with multiple electrodes on its surface.…”

“…Numerous studies forego reliance on commercial EEG devices, opting instead to construct their ear-EEG system with custom-made processing modules [7,34,49,63,67,68,70]. Specifically for in-ear EEG, certain designs are compact enough to be integrated within the earpiece itself, rendering them remarkably wearable and practical for real-world use [47,48].…”

“…Eye state is one of the most clearly observable responses in EEG signals; when eyes are open, EEG signals show an alpha attenuation response (AAR), referring to alpha band power decreasing. Such characteristic allows eye states and the corresponding AAR to be used to check the signal quality of both in-ear [32,34,49,105] and around-ear [4,59,106] devices.…”

Objective:This review paper provides a comprehensive overview of ear-EEG technology, which involves recording electroencephalogram (EEG) signals from electrodes placed in or around the ear, and its applications in the field of neural engineering.Approach:We conducted a thorough literature search using multiple databases to identify relevant studies related to ear-EEG technology and its various applications. We selected 123 publications and synthesized the information to highlight the main findings and trends in this field.Main Results:Our review highlights the potential of ear-EEG technology as the future of wearable EEG technology. We discuss the advantages and limitations of ear-EEG compared to traditional scalp-based EEG and methods to overcome those limitations. Through our review, we found that ear-EEG is a promising method that produces comparable results to conventional scalp-based methods. We review the development of ear-EEG sensing devices, including the design, types of sensors, and materials. We also review the current state of research on ear-EEG in different application areas such as brain-computer interfaces, and clinical monitoring.Significance:This review paper is the first to focus solely on reviewing ear-EEG research articles. As such, it serves as a valuable resource for researchers, clinicians, and engineers working in the field of neural engineering. Our review sheds light on the exciting future prospects of ear-EEG, and its potential to advance neural engineering research and become the future of wearable EEG technology.
