These are small (50cent to quarter sized) devices that measure glucose levels without finger sticks.  Currently, they are used by people with Type 1, Type 2 and pregnant women with Diabetes. The FreeStyle Libre  is the first device that does not require finger sticks. To get the sugar number, a reader is simply waived over the sensor that is usually worn on the back of the upper arm.  It can be worn for 10 days. (  Another model, the Dexacom G6 continuously monitors the blood sugar level and sounds an alarm if it rises or falls too much. Also this model does not need fingerstick calibration.


Implantable Sensors


The new Eversense  CGM system is put just under the skin and will last for 3 months while sending the sugar level wirelessly to a receiver or your smart phone. 


Noninvasive Monitoring


The new/y developed SugarBEAT uses a sticky skin patch CGM sensor that measures the glucose and transmits it to a sensor or to a phone app. This is just being submitted to FDA for approval.


Insulin Pumps


The pumps are usually used by people with Type 1 or women with Pregnancy and Diabetes, however also occasionally they are used by people with Type 2 who need multiple insulin doses per day.

One of the newest models is called Tandem T-slim X2 Pump. These are smaller and  so advanced that they includes a method of automatically calculating the amount of insulin needed at any one time just as the normal pancreas does. It works in tandem with a CGM!!!( It calculates the amount of insulin needed after the CGM reads the glucose level.) This newest pump, the Tandem T- slim X2, can be seen on the web at › products › t-slim-x2-insulin-pump


Smart Pens


Smart Pens like the InPen and Gocap connect with a phone app via Bluetooth and keep track of insulin dose and the time of the dose. InPen even helps the user to calculate the right dose. The pen stores the information on your phone so that it can be shared easily with your doctor. A new reusable insulin pen, NovoPen Echo Plus

is on the way & will store about 3 months worth of insulin treatment data (use of new needles for each injection and a no backflow feature keeps it sterile). For the Plus, the data connects to systems like the Dexcom or Glooko.


Technology and Research are moving closer to a system that works like the normal pancreas and responds to the daily ups and downs of the body’s sugar levels!!
