NIRscan Nano information

Other Parts Discussed in Thread: TMP006, HDC1000

Dear Engineers

I'm doing research to measure blood glucose in non-invasive manner using NIR spectroscopy. I found NIRscan™ Nano Evaluation device is on interest but i need some information to see whether it will help me in my research

-Can i measure and save the NIR spectrum so that i apply signal processing technique over the measured data to determine the level of the glucose?

-Is it possible that i use this device to do non-invasive NIR measurements, like measuring from ear loop, skin, finger,etc...?

-Can i program the device so that it compiles the glucose level ?

Looking further to hear from you

    Mr. Alzaid,

    Each time that a scan is captured by NIRscan Nano using the GUI, the scan intensity and absorbance are writing to a CVS file on the PC. Also, when a scan is initiated on the NIRscan Nano by a press of the button, the scan information is written to the micro SD Card, if one is present. Using the KST NIRnano Bluetooth app, the scan information is saved in the iPhone.

    The CSV file includes:

    • date and time
    • System temperature (in hundredths) from TMP006
    • Detector temperature (in hundredths) from TMP006
    • Humidity temperature (in hundredths) from HDC1000
    • Lamp photo detector value
    • Calibration coefficients
    • Serial Number
    • Scan Configuration Name
    • Start and end wavelength ranges
    • Number of measurement points
    • Number of repeats
    • PGA gain
    • Total measurement time
    • Scan data with each point reporting:
      • Wavelength, Absorbance, Reference Signal, Sample Signal (Intensity)

    For more info see the NIRscan Nano User's Guide.

    Best regards,
    Pedro

    As far as programming the device, all the Tiva and GUI sources are included in the software downloads. You can modify the GUI sources using Qt and the Tiva sources with Code Composer Studio. KST also offers an open source SDK for the NIRscan Nano Bluetooth iOS App.

    Dear Khalid,

    Re last Q: ".. -Can i program the device so that it compiles the glucose level ? .."

    this is a more application specific question.
    pls google for "glucose in blood by nir" to scope the methods of glucose determination.

    IMHO you need not dig in device programming to determine glucose level in blood,
    as it is require alot of non-trivial math, but instead use chemometric methods on the
    external computer/data station.
