Implantable long-term glucose sensor waiting for FDA approval


The days when you needed to prick your fingers and trickle out your precious blood droplets for testing the blood glucose levels are long gone. And now the new implantable device that could monitor your blood glucose 24/7 for more than a year is going to be the state-of-the art biomedical sensor in future market. This instrument developed by University of California, San Diego and GlySens Incorporated can be implanted in the body. The little wonder gadget communicates information about glucose levels in the tissues to an external receiver via wireless telemetry. This device which is yet to be approved by FDA is already being considered as a great breakthrough. This device is 38mm across and 16 mm thick and it could be implanted subcutaneously at the waist or the lower abdomen by a simple outpatient procedure.

How does it work?

  • This platinum sensor is unaffected by tissue encapsulation for more than 500 days
  • It senses Glucose and oxygen from the surrounding tissues that diffuse in it
  • Here the enzyme called glucose oxidase acts on the glucose utilizing oxygen proportional to amount of glucose present
  • The measure of reduced oxygen compared to the background oxygen, recorded by oxygen reference sensor (this device has dual sensors) is then used for estimating the glucose levels


  • Sensor detects glucose levels in patients with Type 1 and Type 2 diabetes
  • In type 1 diabetes body cannot synthesize its own insulin and hence these sensors could be used to adjust dose and...

    timings of insulin injections. This is essential in order to avoid Hypoglycemia due to excessive dose of insulin
  • In type 2 diabetes glucose sensors could help patients to customize their diet and exercise based on the glucose-level fluctuations
  • This device thus limits glucose excursions (glucose level fluctuations) which are usually the cause of long-term problems associated with diabetes.
  • It is also a big relief for the parents whose kids are prone to get nocturnal hypoglycemia since glucose sensors are capable of sending information to a phone that could alert parents about their child’s Glucose levels at night


Dr. David Gough has been the lead person involved in developing this sensor. After Human clinical trials and FDA approval; this device could be a great alternative to the current glucose measurement techniques.  Biggest advantages being its long term functionality and the ability to continually monitor blood sugar content. Diabetes is one of the most ubiquitous diseases and this invention could be a big relief to millions to help them being continually monitored and live healthy.
