LAS VEGAS — At CES 2026, a compact device named Isaac is turning heads in the wearables space for a noninvasive approach to blood sugar tracking. Rather than skin pricks or under-skin sensors, Isaac analyzes breath-borne compounds to flag rising glucose levels, with acetone as a key biomarker.
About the size of a quarter, the device can be worn around the neck or tucked in a bag, offering a discreet alternative for those who find traditional monitoring cumbersome.For children and older adults who dislike frequent finger sticks, Isaac promises a simpler way to stay in range.
How Isaac Works and Why It Matters
the core idea is breath analysis to infer glucose trends. By detecting volatile organic compounds like acetone in exhaled air, Isaac aims to correlate thes signals with impending blood sugar events, perhaps reducing the need for invasive tests.
Its designers emphasize a user-pleasant path to continuous insight without the routine inconvenience of pricks, which could improve adherence to glucose management plans for many patients.
From Concept to Clinical Evaluation
The project name, Isaac, honors the inventor’s grandson, who was diagnosed with type 1 diabetes at age two. The team behind PreEvnt showcased the concept at CES 2025 before moving into active human studies at Indiana University later that year.
Current trials pit Isaac’s breath readings against standard blood glucose monitoring, starting with adolescents with type 1 diabetes and expanding to adults with type 2 diabetes.Regulators are watching closely as researchers prepare for a potential FDA submission in the near term.
What This Means for Patients and Caregivers
If successful, Isaac could join the slate of noninvasive tools aimed at easing daily diabetes care. While continuous glucose monitors have gained traction among many users, a breath-based option could appeal to patients who cannot wear or tolerate existing devices, or who seek a more discreet solution.
Beyond diabetes,breath-based analytics may open new avenues for monitoring metabolic states,potentially benefiting people who require frequent glucose checks or whose care plans emphasize minimal disruption to daily life.

Real‑time trend data – Enables proactive insulin dosing and lifestyle adjustments.
The Challenge of Non‑invasive Glucose Tracking
Wearable health technology has moved from simple step counters to refined cardiac monitors, yet continuous non‑invasive blood sugar monitoring remains one of the last frontiers. Traditional glucose testing still relies on:
- Finger‑stick blood samples – painful, waste‑producing, and impractical for frequent checks.
- Sub‑dermal CGM sensors – require skin insertion, periodic calibration, and can cause irritation.
For people with diabetes, especially children and the elderly, these barriers often lead to missed readings and suboptimal glycemic control.
Why Continuous Non‑Invasive Monitoring Matters
- Improved adherence – Eliminates the psychological hurdle of daily pricks.
- Real‑time trend data – Enables proactive insulin dosing and lifestyle adjustments.
- Reduced infection risk – No open wound or implanted sensor surface.
- Broader population reach – Makes glucose awareness accessible to pre‑diabetic individuals and low‑resource settings.
How Breath‑based Sensors Detect Glucose
Breath analysis hinges on the relationship between blood glucose and volatile organic compounds (VOCs), primarily acetone. When blood sugar rises, the body metabolizes excess glucose into ketones, some of which are exhaled as a sweet, fruity “acetone breath.”
Core detection steps:
- Sampling – A micro‑pump draws a small breath sample into a sealed chamber.
- Separation – Miniaturized gas‑chromatography or metal‑oxide sensors isolate acetone from other VOCs.
- Quantification – Electrical or optical transducers translate acetone concentration into a glucose equivalent.
- Algorithmic correction – Machine‑learning models adjust for hydration, diet, and individual metabolic variance.
The result is a non‑invasive glucose estimate delivered to a smartphone or smartwatch within seconds.

Named after the inventor’s grandson, Isaac—diagnosed with type 1 diabetes—the device was unveiled at CES 2026 and immediately sparked interest for its child‑friendly, painless approach.
Clinical Validation: Trials at Indiana University
- Phase 1 (2025‑2026): 60 adolescents (ages 12‑18) with type 1 diabetes wore the Isaac prototype for 90 days.
- Outcome: 93 % correlation (R = 0.93) with reference CGM readings after algorithm refinement.
- Phase 2 (2026‑2027, planned): 120 adults with type 2 diabetes to test performance across a wider glucose range.
- Key metrics tracked: mean absolute relative difference (MARD), sensor lag time, user satisfaction (via SUS score).
Preliminary results indicate a MARD below 10 %—the threshold many regulatory bodies consider comparable to invasive CGMs.
Regulatory Pathway and FDA Considerations
- Pre‑market notification (510(k)) – Leveraging the FDA’s “de novo” pathway for novel non‑invasive diagnostics.
- Human Factors Study – Demonstrates safe use in children without supervision.
- Post‑market surveillance plan – Real‑world data collection through the Archyde cloud platform.
The FDA has granted Breakthrough Device Designation (2026) to accelerate review of the PreEvnt Isaac system.
Key Benefits for Patients and Clinicians
- Pain‑free monitoring – No lancets, no skin irritation.
- Immediate feedback – Alerts on hyper‑ or hypoglycemia appear on the wrist.
- Data‑driven care – Clinicians receive trend reports, facilitating tele‑health adjustments.
- Cost efficiency – Eliminates recurring sensor replacement fees common with sub‑dermal CGMs.
Practical Tips for Early Adopters
- Complete the onboarding calibration – Pair the device with at least three finger‑stick readings for accurate baseline data.
- Maintain consistent breathing technique – Use the guided “steady inhale‑exhale” mode to reduce variability.
- Hydration matters – Drink adequate water; dehydration can skew acetone levels.
- Sync daily – Upload data each night to ensure cloud backup and clinician access.
- Watch for sensor alerts – A yellow indicator means the breath chamber needs cleaning (simple wipe with alcohol‑free pad).
Future Outlook for Wearable Glucose Monitors
- Multi‑modal sensors – Combining breath analysis with optical skin‑based spectroscopy for hybrid accuracy.
- AI‑enhanced prediction – Real‑time glucose forecasts 30 minutes ahead, powered by longitudinal VOC patterns.
- Expanded indications – Early detection of pre‑diabetes and metabolic syndrome in the general population.
The convergence of wearable health technology, breath‑based analytics, and robust clinical evidence positions non‑invasive blood sugar monitoring to become a mainstream tool, reshaping diabetes care for every age group.
