AI Technical Summary
Existing brain-computer interface signal acquisition devices suffer from problems such as slow response speed, low accuracy and reliability, high cost, high environmental sensitivity, poor durability, small measurable range, and inflexible configuration.
A non-invasive EEG acquisition system using low-cost brass dry electrodes and AgCl electrodes combined with a high-impedance bias circuit, as shown in Figure 1, along with an INA 350 analog front-end based on a PCB board and an STM32L433 microcontroller, was developed. Low-noise, high-impedance electrodes were achieved through 3D-printed goggles. As shown in Figure 2, low-power signal acquisition was achieved through a signal processing device.
This low-power signal acquisition device achieves high response speed, high accuracy, and durability. It is suitable for non-invasive EEG acquisition systems, provides efficient signal acquisition, supports the application of the technology, and achieves low-power technical effects.
