PreEvnt’s isaac breath glucose monitor debuts at CES 2026 tech show
NEWYou can now listen to Fox News articles!
The idea of tracking blood sugar without needles has challenged health technology for years. For people with diabetes, constant monitoring is essential, but the tools remain uncomfortable and invasive. Finger pricks hurt. Traditional continuous glucose monitors are always placed under the skin. This daily burden adds up quickly.
Recently, a small device has attracted attention because it solves this problem in a very different way.

WEIGHT LOSS EXPERTS PREVENT 5 MAJOR TREATMENT CHANGES LIKELY TO EMERGE IN 2026

Why non-invasive glucose monitoring is important
Blood sugar can rise or fall quickly. When changes go unnoticed, risks increase, ranging from long-term organ damage to sudden hypoglycemia. Monitoring can be particularly difficult for:
- Small children
- Elderly
- Anyone who has difficulty with needles
At the same time, blood sugar monitoring has increased among people without diabetes. As GLP-1 medications gain popularity, many people now track their blood sugar levels to understand how food affects their body. The need for simpler tools continues to grow.
Even Apple has spent years trying to bring needle-free glucose tracking to wearable devices. Despite heavy investments, this functionality has not yet arrived.
NEEDLE-FREE BLOOD GLUCOSE CONTROL IS CLOSE TO REALITY

How the PreEvnt Isaac monitors blood sugar using breathing
One of the most talked about health devices today CES 2026 came from PreEvent. His product, called Isaac, takes a non-traditional approach to glucose awareness. Instead of piercing the skin or using optical sensors, Isaac analyzes your breathing.
The device measures volatile organic compounds, particularly acetone, which have long been associated with increased blood sugar levels. This sweet, fruity breath is a known marker of diabetes. By detecting changes in these compounds, Isaac can alert users to potential glucose-related events. The device is small, about the size of a coin, with a loop so it can be worn on a lanyard or attached to clothing or a bag.
The breath-based design aims to reduce the frequency with which users need finger-prick blood tests, while providing early alerts of blood sugar-related changes.
The device is named after the inventor’s grandson, Isaac, who was diagnosed with type 1 diabetes at just 2 years old. The inventor, Bud Wilcox, wanted to reduce the number of painful finger pricks his grandson faced every day. This personal motivation led to years of collaboration with scientists, designers and engineers. Research and development included work with Indiana University under the direction of Dr. M. Agarwal. The goal was simple but ambitious: alert families to blood sugar-related events earlier while reducing the physical and emotional toll of constant testing.
How the Isaac device fits into everyday life
Isaac is designed to fit into daily routines. Users breathe into the device, which processes the reading and sends the data to a companion smartphone app. The app, still in the final stages of development, focuses on awareness and safety. Current features include:
- A calendar to record meals
- A history of breath readings
- Alerts that can notify emergency contacts
This is important because people with diabetes may become disoriented or unable to function during hypoglycemic events. Early warnings give caregivers or family members a chance to intervene. A single charge lasts all day and supports multiple breathing tests. The device comes with a charging pad and a USB-C cable.
Who was Isaac designed for?
According to PreEvnt, isaac is developed for:
- Type 1 diabetics
- Type 2 diabetics
- Prediabetics
It may also appeal to people concerned about their metabolic health. As mentioned, the device is still under development and review by the FDA and is not yet for sale in the United States. The companion app will launch on iOS and Android closer to availability.

Clinical Trials and FDA Review for the Isaac Device
PreEvnt first publicly demonstrated Isaac at CES 2025. Later that year, the device entered active human clinical trials. These studies compare Isaac’s breath alerts to traditional blood sugar monitoring methods.
The trials began with adolescents with type 1 diabetes and then expanded to adults with type 2 diabetes. The company is currently working on a regulatory review with the U.S. Food and Drug Administration. Because this technology is new, PreEvnt is pursuing a de novo path, which makes it possible to evaluate the devices while the standards are still being defined. Regulators have shown keen interest as data continues to come in, according to the company.
Isaac does not claim to replace medical grade glucometers. The device is being developed to complement existing monitoring methods by providing respiratory alerts related to glucose-related changes.

Kurt’s Key Takeaways
Non-invasive blood glucose monitoring has long seemed like a promise of the future that never really comes true. The attention paid to Isaac at CES 2026 suggests that promise may finally be getting closer. If clinical trials continue to produce convincing results and regulators give their approval, breathing into a small device could one day replace at least some finger pricks. For families with diabetes, this change could make daily life easier and safer.
