PGS is currently a development stage prototype and is not available for sale. The PGS is available for technology transfer or for investment purposes.


Photonic glucose sensor

PGS is a glucose sensor technology aimed to provide people with diabetes with continuous monitoring of their blood glucose trends and variations. PGS helps prevent hypoglycemia and provide additional guidance for better glucose self-management.

The PGS sensor is an armband simply worn as a garment to warn a user when it detects a significant drop of its blood glucose level at any time of the day or night. PGS can also be linked to a Smartphone to provide information about glucose level trending up or down. Feedback on how good the glucose control really is can be provided with a computed level of variations measured from the sensor over a selectable period of time.



Good glucose control is a key factor in reducing the risk of the long-term complications of diabetes. PGS prevents most hypoglycemia at the earliest symptoms. It can be a safeguard for child or elder who has difficulty feeling the onset of hypoglycemia.


As a complement to a spotcheck blood glucose meter, the PGS can provide trends continuously (raising or falling glucose levels information).


Unlike other Continuous Glucose Monitors (CGM), the PGS is totally non-invasive. No needle sensors to replace.


PGS armband is small and lightweight and adheres to the skin with a simple adhesive. Weared as a garment.


With a single button operation, PGS is extremely user-friendly. Simply strap with an adhesive, turn on, and be ready to go.

How it Works?

The PGS features a totally non-invasive glucose sensor with continuous alarm monitoring. At the start of the day, simply strap-on the PGS armband to the upper arm. Using near-infrared light technology and other physiological signals, the PGS monitors the relative glucose level trends every 5 minutes and for up to 30 hours on a single charge. On the next day, simply connect PGS to its charger and during the time of a shower it will get ready to be worn again on the next arm.

Daily usage


Start your regular morning routine. Before your shower, place the PGS on its charging craddle. After your shower, simply replace the recharged PGS with a new adhesive label and strap on the sensor.


Carry on your daily diabetes management plan. The PGS continuously check glucose trends.


Whenever you'd like, use your compatible smarphone to check your glucose trend. The PGS will wirelessly transfer the up or down trend information for you to better manage your glucose.

ALARMS (Beep & Vibe)

When PGS detects a potential drop in your blood sugar, it vibrates (and optionally beeps). Perform a blood glucose meter test. Take action as you would normally do in such case.


The PGS keeps a watchful eye while you sleep for your peace of mind. If it detects a critical drop in your blood sugar levels, the PGS vibrates until you click its button and will snooze 10 minutes after.


The PGS straps onto upper arm, with the measuring head in direct contact with the skin.

PGS sends near infrared light which enter and and bounce back out of dermis at a certain angle. Light rays are caught by detectors on the measuring head.

A narrow average angle means that there is less glucose in the dermis.

A wide average angle means that there is more glucose in the dermis.
