- Researchers developed a 3D-printable, hairlike EEG electrode for more reliable brain activity monitoring.
- The new electrode eliminates the need for conductive gel, reducing mess and improving signal consistency.
- Current EEGs use 21 rigid electrodes, which introduce noise with movement and require frequent gel reapplication.
- The hairlike electrode is 300 μm wide, matches hair color, and uses a strong bioadhesive for secure attachment.
- Testing showed the electrode stayed attached for 24 hours, even during showers and exercise, without skin damage.
- The device maintained stable impedance and eliminated motion artifacts, improving signal quality.
- Future goals include developing a wireless version for broader applications in health monitoring and brain-computer interfaces.
