Who said you have to prick your finger to measure blood sugar? The “blood sugar microneedle patch” is here!
"Pricking your finger to take blood" is a necessary process for traditional blood glucose testing, and the operation is relatively cumbersome. And the pain is obvious. Researchers from the University of Waterloo in Canada are developing a blood glucose microneedle patch. new blood glucose monitoring device.
The device is easy to use and can be attached to the arm for up to two weeks. All-weather blood glucose monitoring, blood glucose data can be read at any time on your mobile phone.

Intelligent upgrade! The "microneedle patch" is attached to the arm and can monitor blood sugar in real time
The "blood glucose microneedle patch" being developed uses hydrogel conductive materials as micro-needle A new device for glucose sensing based on the needle platform, which monitors glucose levels in real time through hundreds of tiny microneedles. After three years of exploration, the research team is perfecting this wearable patch to ensure blood glucose detection performance while making it as small as possible (only about 1 square centimeter) so that it can be attached to a person's arm more safely.
Convenient and fast, can be worn by yourself, providing blood glucose monitoring for up to 14 days
Dr. Mahla Poudieh, a developer of new devices and professor of electrical and computer engineering, said that compared with the current CGM patches already on the market, "new microneedle patches" have obvious advantages. For example, it is convenient, fast and can be worn by yourself. Patients can apply the patch on their own without the help of a doctor or nurse, as is the case with some other skin-implanted devices.
And, compared with current devices that generally provide 7 to 10-day monitoring capabilities, “blood glucose Microneedle patch" can provide more accurate and continuous 14-day monitoring results. In addition, because it uses low-cost materials, the price may be cheaper than some patches on the market.
Real-time control of blood sugar to assist disease management
Peman Gawaminejad, a PhD student in engineering at the University of Waterloo who led the work Peyman GhavamiNejad) said: "Blood sugar information is crucial for diabetic patients. By knowing their own blood sugar control, it can help patients and doctors judge whether they need to adjust their diabetes management strategy and whether they need to adjust their medication dosage. With the support of new equipment , we can improve patients' lives through more personalized medicine strategies. By making it easier for people to take control of their own blood sugar levels without pain, ultimately achieving better blood sugar control."
