F or people with diabetes, blood sugar monitoring is a daily — and sometimes hourly — chore. Most approaches are invasive and involve piercing the skin, which can cause pain. In a study recently published in Science Advances, researchers revealed a thin, invisible, and biodegradable patch that successfully measured different concentrations of blood glucose in mice.
The researchers speculated that when combined with a smartphone application, the technology could help patients with diabetes continuously and noninvasively monitor their blood glucose levels.
Many people with diabetes monitor their blood sugar with a standard glucose meter. They prick their fingertips with a hairlike needle, or lancet, to draw minuscule amounts of blood. If done incorrectly, this process can be painful and cause hard calluses.
Other common alternatives are also invasive. The sensor degrades completely roughly every three days. The sensor the researchers designed consists of two layers. The top layer is made from polyvinyl alcohol. The second layer comprises an array of needles which pierce the skin surface but not far enough to reach nerve endings.
This layer is made of silk, a well known biodegradable material. To measure glucose, the team chose a glucose fluorescent GF monomer composed of two parts. The first is a di-boronic acid, which binds to glucose in the interstitial fluid just underneath the skin. The other is a hydrophobic fluorescent molecule, which changes shape and emits fluorescence when glucose binds to the acid.
c The blood glucose variation curve of a volunteer measured by the watch during the daytime compared to true blood glucose values reference obtained from finger blood.
d Glucose concentrations before and after a meal measured by the watch from five volunteers. of five replicates. e Plot of glucose concentrations measured from 23 volunteers by the watch and by a commercial glucose meter. All fingerstick blood tests except the second were performed immediately after meals.
A two-volunteer 1 diabetic and 1 nondiabetic trial was conducted to assess the accuracy of consecutive measurements by the watch. Five fasting glucose levels of each volunteer were measured by the watch within 1.
The two types of results matched well for both volunteers, indicating good accuracy and reproducibility of glucose measurements by the watch in the short term Fig. This result also serves as circumstantial evidence of the reproducibility of the iontophoresis function in the watch.
We further tested the performance of the watch on five other volunteers, measuring their blood glucose levels before and after a meal. The watch successfully captured the increase in blood glucose levels after a meal Fig. To evaluate the accuracy of glucose measurements by the watch with a widely acknowledged criterion, the Clarke error grid was plotted using the measurement results obtained from 23 volunteers Fig.
The results and statistics of measurement by the watch are presented in Fig. S11 and Table S3. The percentage of data points in zone A and zone B of the Clarke error grid, which represents clinically accepted accurate readings and acceptable moderate readings that would not lead to inappropriate treatments, indicates the accuracy of the tested glucose meter.
Remarkably, no experimental data points fell in zone D or zone E, suggesting that the watch yields high-quality measurement results without misleading or false readings The data points are concentrated in zone A Additionally, all volunteers reported a comfortable wearing experience resembling that of commercial smartwatches, with no obvious sensational difference e.
To verify that daily body motions do not impair the sensing performance of the watch, we compared the measurement results from two watches, one worn on a static arm and the other on a moving arm, of the same nondiabetic volunteer. The difference between the average results of six measurements each from the two watches was 2.
S12 , comparable to the error of the same sensor between repeated measurements, indicating that daily body motions do not affect the performance of the watch. In summary, we developed a highly integrated glucose monitoring watch and achieved noninvasive continual blood glucose monitoring with clinically acceptable accuracy.
Reverse iontophoresis-based ISF extraction by a flexible glucose sensor patch allows painless glucose detection, and the watch-like design ensures comfortable daily wear, facilitating continual glucose monitoring. Real-life testing of the watch on 23 volunteers revealed Subsequent efforts could be made in a few directions; for example, the accuracy could be improved by providing customized models to accommodate potentially interfering factors such as age, gender 38 , exercise 39 , and illness The PCB could be miniaturized and integrated into existing smartwatch models to create a truly noninvasive continuous glucose monitoring smartwatch.
All reagents were used as received. The fabrication of the electrodes is illustrated in Fig. First, the polyimide PI film was cleaned with acetone, ethanol, and ultrapure water.
Then, the electrode and wire areas were defined by a photolithographed layer of positive photoresist AZ Finally, another layer of positive photoresist AZ was photolithographed onto the nonelectrode areas to insulate the wires.
For the working electrodes, three modification steps were performed sequentially, coating the Au electrode with a Prussian blue PB layer, a GO x selective membrane, and a Nafion film. PB was electrodeposited onto the Au electrodes at 0. The designated counter electrodes were left unmodified.
where D m is the mass diffusive coefficient and C g is the glucose concentration. As glucose is rapidly consumed in the extracted ISF, the mass transfer pattern quickly switches from a semi-infinite diffusion model to a finite diffusion model, i. Taking semi-infinite diffusion and the boundary effect into account 36 , the following equation is obtained using the Laplace transform:.
The switching of one of them from 1 to 0 and the other from 0 to 1 represents the complete switching of the diffusion model applied, i. The PCB circuit is based around the STM32LK8 bit microcontroller Texas Instruments module 3 in Fig. In the schematic diagram of the microcontroller interface, PA1 and PA5 are connected to the working electrodes for amperometric signal reading, and PA8 is connected to the constant current source for current delivery for reverse iontophoresis Fig.
The Bluetooth chip is connected to pins PA2 and PA3 of the microcontroller to achieve wireless transmission to a cell phone. The signals are further transmitted and processed by the filter circuitry Fig. On the sensor interface, pins 1, 5, 6, and 12 correspond to the extraction electrodes; pins 2 and 11 correspond to the counter electrodes; pins 3 and 10 correspond to the working electrodes; and pins 4 and 7 correspond to the reference electrodes Fig.
A mobile application was designed for a better user experience. As shown in Figs. In addition, the application is capable of storing historic data and plotting the trend of blood glucose over the period of wearing.
The on-body testing of the watch was performed in compliance with the protocol that was approved by the institutional review board of China-Japan Friendship Hospital K Thirteen diabetic patients aged 40—60 were recruited from China-Japan Friendship Hospital, and 10 nonpatients aged 20—40 were recruited within Beihang University.
Six fingerstick blood samples were taken from each subject and measured by a commercial glucose meter Accusure , Yuwell Co.
The values obtained with the commercial glucose meter and with our watch were recorded and further analyzed.
To test the reproducibility of the reverse iontophoresis function, we carried out volunteer trials. Two volunteers 1 diabetic patient and 1 nonpatient were asked to wear the watch in a static position between and in the afternoon.
Each watch was able to run 5 blood glucose tests during the 1. was performed for each volunteer at each time point when the watch ran its glucose measurement. We conducted further experiments to verify that body motion did not cause inaccurate test results.

Created by startup co-founder Dr. Werner Mäntelethis technology has shown in research from that it has comparable accuracy to the minimally invasive FreeStyle Libre Flash glucose monitor from Abbott Diabetes.
The Dutch startup known as NovioSense is working on a glucose sensor that is placed under the lower eyelid, from where it can wirelessly send glucose measurements directly to a smartphone. The NovioSense device consists of a flexible metal coil just 2 centimeters long that contains nanosensors inside.
The coil is covered by a protective layer of soft hydrogel, and it could measure constant changes in glucose levels from tear fluid using the same enzyme technology employed in conventional glucose test strips.
Clinical trial research published in late shows promising results for the technology and accuracy similar to the FreeStyle Libre, but there are few details available beyond that. This Silicon Valley, California-based startup is developing a noninvasive wearable wristwatch called LifeLeaf. The company says it can detect blood glucose levels, blood pressure, heart rate, sleep apnea, and more by using sensors already on the market and an additional light sensor to enhance accuracy.
Their phase 1 product is aimed at consumers and people with prediabetes, and phase 2 will be for type 2 PWDs and eventually also those with type 1, with high and low alerts and guidance. The company has conducted clinical trials around the world, and at last count, was aiming for FDA clearance by June Out of Wales, a startup called Afon Technology is developing a sensor that would fit inside a smartwatch band to monitor glucose levels.
The company is working on clinical trials outside the United States, with plans for a launch starting in mid Afon shares feedback from Dr. But that buzz may finally be coming true soon. According to a January reportApple may be working on their own glucose monitoring tech that would use an integrated optical glucose sensor.
The report has some fascinating visuals on what the Apple Watch display could look like. Samsung may have its sights on this tech, too. This January news report states:. It is a no-blood sampling method that detects the level of glucose in the blood without blood collection using an optical sensor, and is expected to contribute to the health management of the general public as well as diabetics.
There had been talk years back about a Samsung and Medtronic Diabetes partnership aimed at integrating glucose data into Android watches, but that relationship faded without any product materializing beyond prototypes. There are numerous other small companies and universities currently working on noninvasive glucose monitoring technology, too.
DiabetesMine has been covering attempts at noninvasive diabetes tech sinceand a couple of the gadgets that captured headlines at the time remain legendary.
The first and best-known example is the infamous GlucoWatch. It was later recalled by the FDA. Another notable name in noninvasive CGM tech for several years was C-8 MediSensors based in San Jose, California. This gadget promised to use light to identify and analyze glucose molecules under the skin via interstitial fluid, just like other traditional CGMs.
This company even obtained European CE Mark approval inbut a launch never materialized and, eventually, the company went bankrupt a year later. Many of the C-8 scientists moved on to other companies like Apple and Google, before the company eventually rebranded and relaunched as C-Eight without any focus on noninvasive glucose monitoring.

| Bloomberg - Are you a robot? | One such CGM is called GlucoTrack by Integrity Applications, which measures blood glucose via your earlobe. Other types of technologies may be seen soon to help improve diabetes management without the need for finger pricks. Read more about CGMs and how to choose one from DiabetesMine. A CGM is a type of meter that does not require a blood sample. Most CGMs detect glucose through interstitial fluids in skin tissues. Noninvasive glucose meters such as CGMs are considered both convenient and effective, though they may not be as accurate when compared with traditional meters. Some CGMs have the capability of connecting to and downloading blood glucose information to your smartwatch. Depending on your plan, you may still have out-of-pocket costs. You may ask the pharmacist or manufacturer about possible coupons and discounts to help offset the costs. While traditional blood glucose meters remain standard, noninvasive options are continuously being developed to make checking your blood glucose easier and less painful. Depending on the type of meter you choose, you may have to wear a sensor on different areas of the body and switch it out after a certain amount of time. Talk with your doctor about your concerns with blood glucose monitoring , and whether a noninvasive meter may better fit your needs.

Keep in mind, there are ambitious new companies emerging in this space regularly, despite decades of others trying unsuccessfully. At the big Consumer Electronics Show CES in early January , an artificial intelligence company based in British Columbia named Scanbo gave a glimpse of its technology that would use a second noninvasive finger measurement instead of a traditional blood drop required to measure glucose. The company has developed a prototype that combines a 3-lead ECG measurement and a Photoplethysmogram PPG used to detect blood volume. You just put your fingers on the flat white sensors and the system uses a set of algorithms to analyze and offer insight on glucose values. Another new company making headlines is Hagar Technology , based in Israel, which received Food and Drug Administration FDA fast track designation last year after a series of investor fundraising.

Out of Germany, DiaMonTech has developed a system that uses molecular spectroscopy — the science of absorption of light by molecules — to detect glucose molecules through the skin. Created by startup co-founder Dr. Werner Mäntele , this technology has shown in research from that it has comparable accuracy to the minimally invasive FreeStyle Libre Flash glucose monitor from Abbott Diabetes. The Dutch startup known as NovioSense is working on a glucose sensor that is placed under the lower eyelid, from where it can wirelessly send glucose measurements directly to a smartphone. The NovioSense device consists of a flexible metal coil just 2 centimeters long that contains nanosensors inside. The coil is covered by a protective layer of soft hydrogel, and it could measure constant changes in glucose levels from tear fluid using the same enzyme technology employed in conventional glucose test strips. Clinical trial research published in late shows promising results for the technology and accuracy similar to the FreeStyle Libre, but there are few details available beyond that. This Silicon Valley, California-based startup is developing a noninvasive wearable wristwatch called LifeLeaf. The company says it can detect blood glucose levels, blood pressure, heart rate, sleep apnea, and more by using sensors already on the market and an additional light sensor to enhance accuracy. Their phase 1 product is aimed at consumers and people with prediabetes, and phase 2 will be for type 2 PWDs and eventually also those with type 1, with high and low alerts and guidance. The company has conducted clinical trials around the world, and at last count, was aiming for FDA clearance by June Out of Wales, a startup called Afon Technology is developing a sensor that would fit inside a smartwatch band to monitor glucose levels. The company is working on clinical trials outside the United States, with plans for a launch starting in mid Afon shares feedback from Dr. But that buzz may finally be coming true soon. Sounds an awful lot like how smartwatches detect irregular heart rate rhythms before advising users to seek an official diagnosis from a doctor. While Big Tech likes to disrupt and break things, medicine does not. It took nearly two decades for CGMs to be deemed accurate enough for use as a primary real-time blood sugar monitor. Neither Klonoff nor Mastrototaro felt confident enough to give any predictions as to when we might see noninvasive blood glucose monitoring on a smartwatch you can actually buy. The milestone Bloomberg referred to was Apple purportedly developing an iPhone-size prototype, dramatically reducing the size of the device that previously had to rest on a table. This is all speculation, but if it were true, Apple has a lot of work left to do. First, Apple would need to shrink down this prototype to fit in the Apple Watch. More data from the smaller prototype would need collecting, before ideally publishing the results in a peer-reviewed journal. Everything would have to be reviewed by the FDA. And this is if everything goes swimmingly, without any setbacks or errors that require the company to go back to the drawing board. Skip to main content The Verge The Verge logo. The Verge homepage.

Testing without a pinprick. The glucose signal in the biological haystack. Smartwatches shine light into the skin to measure biometrics like heart rate and blood oxygen levels. Poor skin contact, movement, and stray light can throw off measurements. Regulatory clearance means adjusting expectations.
