Goals

• Read interstitial glucose using near-infrared (NIR) light emitting diode (LED) and a luminosity sensor
• Determine accuracy and precision, comparing against finger pricks and potential saline solutions
• Learn to spec and implement the main components and their supporting components with an Arduino

Glucose Measurement

NIR LED will shine light into the skin which will reflect off of the materials in the skin and go into the luminosity sensor. The Arduino will analyze the absorption spectrum in the form of luminosity, with units of lux.

Glucose absorbs molecules at specific wavelengths in the near-infrared spectrum (700 - 2500nm), so given a calibration, glucose in a specific person can be determined to within some accuracy (TBD).
