Pain Free Sugar Level Monitoring

Pain Free Sugar Level Monitoring

Listed below are some of the methods that can replace the traditional form of blood sugar test. 

 

 

Tear Testing

 

 

There is a second category of implanted devices that offer a similar CGM experience, only with a different input method. We are talking about devices that revolve around testing tears for glucose content. It is well known that tears contain trace amounts of glucose and can, therefore, be considered a stable source of diabetic information. One of the most promising examples of tear based glucose testing is the system developed by NavioSense.

 

 

Their implementation involves the use of a flexible miniature sensor that is placed in the lower eyelid. The sensor is shaped in a flexible metal coil design that is covered with a hydrogel layer. The hydrogel contains an enzyme, called glucose oxidase which is also used in regular blood sugar tests.

 

When this enzyme detects glucose in the tears, it produces an electric signal which can be picked up and transmitted to a smartphone using an NFC chip. The brand has already proven the validity of their claims in Phase 1 & 2 trials. One of the major areas of focus for the team now is shrinking the wireless components enough to fit into the sensor tip. Once that is done, the device will be ready for final testing and production.

 

 

Radio Wave Testing

 

 

While implanted devices and tear testing technologies do provide a stable glucose count, they still require some level of input from the patient in the form of tears and/or interstitial fluids. This can’t be classified as completely non-invasive, which is why some companies are experimenting with a third kind of measurement, which bypasses all physical interactions and relies solely on radio waves to deliver glucose readings.

 

 

An example of this technology is a product called GlucoWise. To use it, all you have to do is place it on the skin between the thumb and forefinger. Once in place, the device transmits low-power radio waves that pass through the tissue and are captured by a sensor on the opposite side of the device. This is similar to devices that are attached to and provide relevant medical data.

 

 

This data about the characteristics of the blood within the flesh is analysed and turned into glucose readings using a special algorithm. The company has conducted several successful trials showcasing its validity, and will soon bring the product to the market. Once that happens, it will launch a whole new wave of radio-wave based medical devices.
