how can i check glucose without blood?
According to the International Diabetes Federation, diabetes is a global challenge. More than 589 million people worldwide live with this disease.1
To monitor blood glucose levels, invasive methods such as pricking the finger or wearing a continuous glucose meter are common.
The D-Pocket uses our unique approach to provide a pain-free, non-invasive measurement.
how does non-invasive glucose monitoring work?
Our non-invasive method detects how light interacts with glucose molecules in the body.
The technology is based on the well researched physical methods of spectroscopy. We have further developed these methods to make non-invasive blood glucose monitoring possible. We call it "photothermal detection". Our CSO and Co-Founder Prof. Dr. Werner Mäntele and his team from Goethe University Frankfurt have been researching the technology for over 15 years. We are now developing a medical product on this basis.
Measurement Process
After you place your finger gently on the sensor, a light beam is directed to it. Glucose in your skin transforms that light to heat. This minimal change in temperature (you won’t notice it) is measured by our detection system. Our device then calculates your blood sugar level based on the temperature change.

It’s important that every detail has the highest level of precision in order to get accurate readings. That is why we only work with the best companies worldwide and manufacture our devices locally. DiaMonTech is truly “made in Germany”.

A peek behind the curtain
This is the heart of our technology. It looks easy and works magically, but we did put a lot of thought into it.
This is our sensor surface – a clear, skin-friendly crystal that guides the infrared light onto your skin. Gently put your finger or thumb on it and keep it still while the screen displays the measurement progress.
This is the heart of our measurement system: A high-tech, state-of-the-art quantum cascade laser (QCL) that emits infrared light in a spectral range that is absorbed by glucose. This type of laser radiation is safe for the eyes and for the skin.
This is the optic lens that guides the infrared laser beam to the sensor crystal and further into the skin.
This tiny red light laser is part of our detection system.
This is a position-sensitive detector that registers the slightest deflection of the red light beam caused by the temperature change induced in the skin.
The whole system is mounted on an “optical bench” that ensures the highest precision during measurements.

IS THERE CLINICAL DATA TO PROVE THAT THE TECHNOLOGY WORKS?
Our last clinical study shows that DiaMonTech’s non-invasive system can reach medical-grade accuracy, comparable to early invasive CGM devices.2
DiaMonTech’s non-invasive system demonstrated a comparable performanceas early (invasive) CGM systems, which have been approved by the FDA and Notified Body in the EU. The non-invasive method achieved MARD values of 20.7% and 19.6%.3 This marks the first time a non-invasive device can show similar accuracy as an invasive device in a real-life comparable study setting. We continue to further develop and refine our system to achieve even greater accuracy and reliability in the future.
faqs about the d-pocket
When can I purchase the D-Pocket?
The D-Pocket is currently still under development. After that, clinical studies and certification processes have to be carried out. We are well on the way, but need more time and cannot yet give a date when the D-Pocket will be available. This also applies to the D-Sensor.
As soon as there is news, our newsletter subscribers will be the first to know!
Can I test DiaMonTech's technology?
Unfortunately not yet. The technology is first tested internally and in clinical studies. If we are looking for testers, we will do so through our website or newsletter.
Where will I be able to buy the D-Pocket? Is there a waiting list?
The D-Pocket will initially be marketed in European countries and in the USA.
There is no waiting list, but our investors will have priority access to our first devices.
Will my health insurance cover the cost of the D-Pocket?
We are already in contact with health insurance companies and are confident that the costs for the D-Pocket will be covered.
What distinguishes DiaMonTech's technology from that of its competitors?
DiaMonTech uses a completely new mid-infrared laser technology to scan the tissue fluid in the skin and detect glucose molecules. Short pulses of infrared light are sent to the skin, which are absorbed by the glucose molecules. This generates heat waves that are detected using our patented IRE-PTD method. This guarantees that no other molecules are mistaken for glucose, which ensures the high selectivity of our method.

What are the benefits of frequent glucose measurement for people with diabetes?
Regular glucose monitoring is an essential component for effective diabetes management and reducing complications. The Diabetes Control and Complications Trial and a Follow-up Study (DCCT) showed that intensive monitoring of blood glucose reduced the risk of complications of eye disease by 76%, kidney disease by 50%, and nerve disease by 60%. A similar study (EDIC) showed that thorough control of blood glucose reduced all cardiovascular events by 42% and heart attacks by 57%.
What are the benefits of glucose monitoring for people without diabetes?
Glucose monitoring for people without diabetes can provide the following benefits:
1. Health awareness: Tracking blood glucose can help develop awareness of the impact of certain foods on blood glucose and promote a balanced diet.
2. Energy and performance enhancement: a stable blood glucose curve can help to better meet energy needs in training and everyday life, which can support performance enhancements.
3. Health optimization: regular blood glucose control can help balance hormones, improve well-being and possibly reduce the risk of certain diseases.
4. Early detection of problems: By monitoring blood glucose fluctuations, potential health problems can be detected and acted upon early.
A health care professional should always be consulted to address specific health issues when in doubt.
Does DiaMonTech technology require test strips or other disposables?
No, no consumables or disposables are required. It may be necessary to superficially clean the sensor from time to time. This can be done with small wipes that are also used for cleaning glasses.
The skin is so complex. How do you make sure that only glucose is measured?
True. Skin is a complex system of layers with various properties. The uppermost layer, called the stratum corneum, consists of dead skin cells that are gradually repelled and finally end up in your vacuum cleaner. The layers below are called the stratum granulosum and the stratum spinosum. They contain living cells surrounded by a liquid called interstitial fluid (ISF). ISF has a much simpler composition than blood and contains glucose at a level of 85-90% of blood glucose. Moreover, ISF glucose rapidly follows blood glucose changes, typically in less than five minutes. The selectivity given by the mid-infrared spectroscopy together with the use of our patented IRE-PTD detection technique ensures that we really measure glucose.
Does the laser generate heat? Are there any health risks?
No need to worry. The amount of heat deposited in the skin upon absorption of the light beam by glucose molecules is so minimal that you cannot feel it or measure it with a conventional thermometer. The heat we mention that is registered by our device amounts to less than 1/1000 of a degree Celsius (ºC).
Do the measurement results change due to the surrounding temperature?
The system is made to work at any moderate ambient temperature, i.e., from 10ºC to 30ºC. A slight loss of precision may occur for temperatures lower or higher than this range, but these are inherent to the impact of the temperature on capillary blood flow rather than the measuring process itself.
The D-Pocket includes basic calibration by the manufacturer. To increase precision, users should calibrate the measurement for their skin type. The D-Pocket software stores your calibration and measurements locally on the device without third party access. If desired, data can be automatically uploaded to a secure online database. Users can choose to share selected data with medical professionals, family members or friends.
Do I need a separate (minimally) invasive measurement device if I use the D-Pocket?
You may keep your separate invasive blood glucose measurement device in case you want to perform a calibration of the D-Pocket from time to time. However, it’s important to note that most invasive glucose test strip systems are only moderately precise. Calibration with a professional glucometer at your diabetologist is always the better option.
