Thermoreversible biogel may solve a hairy problem for wearable brain-monitoring systems

AI Summary

Researchers have developed a thermoreversible biogel that can improve electrical contact quality for wearable brain-monitoring EEG systems by mitigating issues caused by hair and drying gels, which may enhance reliable brain activity monitoring for healthcare practitioners.

A vital tool for health care practitioners, electroencephalography (EEG) systems measure electrical activity in the brain through electrodes placed on the scalp, but getting reliable readings can be surprisingly difficult. Hair interferes with contact between the electrodes and skin, and the gels used to improve those connections often dry out over time, weakening signal quality.
