Wireless near-infrared spectroscopy (NIRS) systems can help to reduce movement artifacts, and distraction due cables. Utilizing Embedded Linux (EL) can reduce size, development time, cost of a project and allow portability. The goal of this project is to develop a low-cost wireless small-sized NIRS system using EL and a Smartphone as the interface. This was achieved using a BeagleBone Black (BBB) with a deployed custom EL that: (1) controls two sources, (2) receives data from photodetectors (PDs), (3) processes, stores and transmits data via Bluetooth to an Android Smartphone. This device was implemented in under US$150 and its dimension was 9x5.5x4 cm. This is considerably cheaper and smaller than most of commercial NIRS systems. It can be applied in functional NIRS research and home care. More importantly our novel implementation of EL in NIRS will open up opportunities to further develop instrumentation using the modular nature of the Linux.
