biosignalsplux fNIRS Pioneer Kit with near-infrared spectroscopy sensor

Product Information

biosignalsplux fNIRS Pioneer Kit

Description:

The fNIRS Pioneer Kit provides a complete set of equipment for acquiring signals using the biosignalplux fNIRS sensor (functional near-infrared spectroscopy). It includes a 4-channel biosignal splux hub, the fNIRS sensor, a hub charger and a Bluetooth dongle from PLUX.

The fNIRS sensor is a user-friendly, non-invasive and portable unit that uses two emitting LEDs in the red and infrared spectrum to measure the reflection of light in the cortical tissues. This method enables the estimation of blood oxygen saturation in the monitored brain region or tissue. The sensor provides a non-intrusive method for monitoring brain activity and is applicable in various research fields such as biomedicine, psychophysiology and other functional neuroimaging applications.

Developed for Developers & Researchers:

Other than most biosignalsplux sensors, which provide a pre-conditioned analog output, this sensor provides a digital output signal which can be received via SPI. Although it has been designed for signal acquisitions conducted on the forehead, the light intensity of each electrode can be set individually using the biosignalsplux API. This allows one to adjust the light intensities when using this sensor on other regions or research applications with different requirements.

Developed in Cooperation with Charles River Analytics:

For the development of this sensor, PLUX has joined Charles River Analytics (CRA) to provide a new affordable miniaturized FNIRS sensor which allows acquisitions of high-quality brain activity data even in settings with heavy physical movement involved – all while keeping the cost of the sensor at a fraction of currently available FNIRS systems.

Together with research partners at CRA and the McLean Hospital (Harvard Medical school), the development and out-of-the-lab results of this sensors have been thoroughly investigated. Those results are presented in the research team’s paper “A System to Monitor, Extract, and Decode Indicators of Cognitive Workload (MEDIC) in Realistic, High-motion Environments”.
