Noninvasive Blood Sugar Monitoring Devices
There’s more than one way to test your blood sugar, and not all require pricking your finger. There are many noninvasive blood sugar monitoring devices that are being researched and may soon be available.
This article contains a list of noninvasive blood sugar monitoring devices currently in development.
Technologies for noninvasive blood sugar monitoring devices include:
- fluid analysis
Radiation methods for noninvasive blood sugar monitoring devices include:
- near-infrared light (NIR) spectroscopy
- far-infrared light (FIR) spectroscopy
- radio wave impedance
- optical rotation of polarized light
Fluid extraction methods for noninvasive blood sugar monitoring devices include:
- fluid extraction from skin
- interstitial fluid harvesting
- measuring acetone in breath
Blood Sugar Monitoring Devices in Development as of 2014.01.22
- earlobe sensor uses ultrasonic, electromagnetic and thermal technology to measure physiological phenomena correlated with blood sugar levels
- does NOT employ optical technology, like other blood sugar monitoring devices
- collects other information such as ambient temperature
- approved for use in EU, but not yet available on the market
- seeking FDA approval
- earlobe sensor
- Not yet cleared for marketing in the US
- Socrates released news in December 2013 that they have a working prototype and will file for FDA clearance in 2014.
- nanometer-thick films consisting of two polymers that react with acetone
- After an initial calibration, readings are performed noninvasively using optical technology to measure blood glucose levels
- Works by measuring changes in near-infrared light that it shines through the finger. (Changes are correlated with blood characteristics; glucose in this case.)
- Contact lens measures glucose in tears
- Google currently “in discussions with the FDA”
Beyond the devices in development, more are yet to come following current research in noninvasive measurement technology. Let us know if we have missed any noninvasive blood sugar monitoring devices currently in development.
