This technology describes a human body signal sensing sensor comprising a flexible substrate, non-reactive metal electrodes, and a surface component attached to the electrode surface to expand its area.
Conventional electrodes faced the challenge of a low signal-to-noise ratio when measuring human bioelectrical signals.
This technology increases the electrode surface area and capacitance through methods such as electroplating, ion etching, and nano-particle coating, thereby enhancing human signal measurement sensitivity and reducing noise.
