Conformal in-ear bioelectronics for visual and auditory brain-computer interfaces

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: July 14, 2023

Brain-computer interfaces (BCIs) have attracted considerable attention in motor and language rehabilitation. Most devices use cap-based non-invasive, headband-based commercial products or microneedle-based invasive approaches, which are constrained for inconvenience, limited applications, inflammation risks even irreversible damage to soft tissues. Here, we propose in-ear visual auditory BCIs based on bioelectronics, named as SpiralE, can adaptively expand spiral along the meatus under electrothermal actuation ensure conformal contact.

Opportunities and Limitations of Mobile Neuroimaging Technologies in Educational Neuroscience

Mind Brain and Education, Journal Year: 2021, Volume and Issue: 15(4), P. 354 - 370

Published: Oct. 5, 2021

As the field of educational neuroscience continues to grow, questions have emerged regarding ecological validity and applicability this research practice. Recent advances in mobile neuroimaging technologies made it possible conduct neuroscientific studies directly naturalistic learning environments. We propose that embedding a cycle (Matusz, Dikker, Huth, & Perrodin, 2019), involving lab-based, seminaturalistic, fully experiments, is well suited for addressing questions. With review, we take cautious approach, by discussing valuable insights can be gained from technology, including electroencephalography functional near-infrared spectroscopy, as challenges posed bringing methods into classroom. Research paradigms used alongside technology vary considerably. To illustrate point, are discussed with increasingly designs. conclude several ethical considerations should taken account unique area research.
