BCIwiki (bciwiki.com) — A stretchable, hair-compatible multichannel EEG platform called MindStretcH showed consistent task-related brain activity with no measurable deterioration in recording quality across longitudinal motor-imagery recordings and repeated online brain-computer interface (BCI) experiments, researchers at The University of Texas at Austin reported in Science Advances on October 2, 2026 (PMID 42826206, DOI 10.1126/sciadv.aee1540).
Reliable BCIs need EEG sensors that keep conformal, low-impedance contact through hair, motion and repeated use, the authors wrote. MindStretcH integrates a kirigami-patterned elastomeric mesh, deformable eutectic gallium-indium (EGaIn) interconnects and detachable conical hydrogel electrodes. According to the abstract, the system adapts to different head shapes, preserves electrical performance under substantial mechanical deformation and maintains stable electrode-scalp contact over prolonged use.
The team says the results establish MindStretcH as a reusable platform for long-term EEG monitoring and BCI applications in laboratory, clinical and home settings.
