The FNIRS (Functional Near-Infrared Spectroscopy) sensor is an easy-to-use sensor which uses two emitting LEDs, one in the red region and the other in the infrared region of the spectrum, to measure the red and infrared light reflectance in the cortical tissue. It provides a non-intrusive and non-invasive method to estimate the local oxygen saturation level in the blood to derive information about the activity of the perfused tissue, for example, to measure and track the activity of a specific brain region by measuring variations in oxygen saturation levels. The sensor is primarily designed for measurements on the forehead.
The reflected light of each one of these LEDs is absorbed by a photodiode and then this current is converted into a digital value that is sent via SPI. Additionally, the acquired sensor data can be used to extract heart rate information.
This sensor has been developed in cooperation with the R&D company Charles River Analytics to provide a new miniaturized FNIRS sensor allowing acquisitions of high-quality data in brain activity-tracking applications while keeping the costs at a fraction of current systems’ costs.
- Adjustable LED intensities
- Accurate signal acquisition on the forehead
- Pre-conditioned digital output
- High signal-to-noise ratio
- Versatile form-factor
- Medical-grade raw data output
- Dual LED Design: 1 red & 1 infrared LED
- Red LED Wavelength: 660nm
- Infrared LED Wavelength: 950nm

- Cable Length: 100cm±0.5cm (customizable; extra costs may apply)
- Connector Type: UC-E6 (male; must be connected to a biosignalsplux acquisition unit)
This sensor is not a standalone sensor and requires the use of a biosignalsplux acquisition unit in order to acquire any data. It can be included in the following biosignalsplux kits which come with all the needed hardware and accessories for data acquisition:
This sensor can be purchased additionally for the following kits:
The development of this sensor is based upon work supported by the United States Army Medical Research and Materiel Command under Contract No. W81XWH-14-C-0018 and United States Air Force under Contract No. FA8650-14-C-6579.
