Isaac, which is meant to monitor blood glucose levels using just the breath of the user, also has a custom phone app. It comes small enough to be worn on an included lanyard or pocket clip and reduces the need for or frequency of fingersticks for people with diabetes.
The Oxnard, California-based company plans to unveil the device at CES 2025.
PreEvnt, a subsidiary of Scosche Industries, designed Isaac for people with type 1, type 2 and pre-diabetes. It can also help those who wish to monitor their blood glucose levels — something for which the industry has seen interest rise following the release of over-the-counter continuous glucose monitors (CGMs) from Abbott and Dexcom.
Isaac provides real-time readings of blood glucose levels to help users make informed decisions about diet and exercise, according to PreEvnt. The technology leverages patented selective gas-sensing MOx technology by Nanoz. It uses volatile organic compound (VOC) detection (specifically acetone) from exhaled breath to identify elevated blood glucose levels. The device’s custom iOS and Android app works to measure, track and share data with family members and physicians.
Additionally, PreEvnt says the app provides real-time alerts if blood glucose levels rise, along with customizable notifications. The rechargeable device comes with its own USB-C charging cable and cradle, typically requiring one charge that lasts all day.
Isaac remains investigational and under development and awaits FDA review. The FDA last year warned against the use of unauthorized devices to measure blood glucose. In its warning, the agency outlined the risks related to using smartwatches or smart rings for this purpose. Such devices may claim to measure blood glucose levels without piercing the skin. These devices are different from smartwatch applications that display data from FDA-authorized blood glucose measuring devices like CGMs.
“By identifying and analyzing the [VOCs] in breath, we can develop sensors that provide early and accurate detection of glycemic conditions,” said Dr. M. Agarwal of Indiana University, who directed research that helped develop the technology. “This technology mimics the capabilities of diabetes alert dogs, offering a noninvasive and reliable monitoring solution.”
