1. A sensor module for brain activity measurement, comprising:
a main electrode base; and
a plurality of pins protruding from the main electrode base,
wherein the plurality of pins is arranged such that, when applied on a subject, each pin of the plurality respectively makes contact with skin of the subject or is in close proximity with the skin of the subject,
wherein the main electrode base comprises electronic circuitry for near infrared spectroscopy (NIRS) measurements and electronic circuitry for electroencephalography (EEG) measurements,
wherein the electronic circuitry for NIRS measurements and the electronic circuitry for EEG measurements are connected to the plurality of pins,
wherein the plurality of pins comprises pins that are respectively configured to conduct both light and electricity,
wherein the pins configured to conduct both light and electricity each respectively include (i) an outer, electrically conductive layer and (ii) an inner waveguide core, and
wherein the pins configured to conduct both light and electricity are configurable for NIRS measurements or EEG measurements.
