On a recent Wednesday, the FDA issued a cautionary statement advising against the use of smart rings and smartwatches that purport to offer noninvasive blood glucose measurement, highlighting potential inaccuracies. The agency recommends that consumers avoid purchasing these devices for glucose monitoring and instead stick to traditional, skin-prick methods.
The FDA's caution is rooted in the critical importance of precise blood glucose readings for individuals managing diabetes. Inaccurate data could lead to significant mismanagement of the condition. For example, incorrect insulin or medication dosages based on faulty readings could precipitously drop blood glucose levels, potentially resulting in severe consequences such as mental confusion, coma, or even death within hours.
Apple, a major player in the wearable technology market, has shown a keen interest in integrating noninvasive glucose monitoring into its Apple Watch. Patent applications from 2021 reveal Apple's efforts to develop sensors using terahertz electromagnetic radiation for noninvasive glucose tracking. By February 2023, Apple reportedly achieved a "proof of concept" milestone. Furthermore, in September, Apple tasked Tim Millet, its vice president of platform architecture overseeing Apple Silicon development, with leading the project on the Apple Watch glucose tracker.
