Neuromonitoring in naturalistic environments is of increasing interest for a variety research fields including psychology, economics, and productivity. Among functional neuromonitoring modalities, near-infrared spectroscopy (fNIRS) well regarded its potential miniaturization, good spatial temporal resolutions, resilience to motion artifacts. Historically, the large size high cost fNIRS systems have precluded widespread adoption technology. In this article, we describe first open source, fully integrated wireless headband system with single LED-pair source four detectors. With ease operation comfort mind, encased soft, lightweight cloth silicone enclosure. Accompanying computer smartphone data collection software also been provided, hardware has validated using classic tasks. This wear-and-go design can easily be scaled accommodate larger number channels opens door collecting during routine activities conditions.
