The author's mention of the Hawthorn Effect fascinated me; I hadn't considered that with devices your care team can monitor.
It will change a lot of lives when some device that doesn't draw blood can continuously monitor glucose, like a smartwatch.
- privatelypublic 1y agoPretty sure optical glucose is already a thing- it's just not very accurate yet.

Existing smart watches that claim to do this are basically garbage. Just use a random number generator instead. Apple and Samsung are supposedly working on it: https://www.forbes.com/sites/davidphelan/2025/01/26/samsung-reveals-game-changer-blood-glucose-monitoring-to-outdo-apple-watch/ https://www.forbes.com/sites/davidphelan/2025/01/26/samsung-... But it seems to be hard and from what I have seen the new Galaxy Watch 8 won't have this feature.
- leakycap 1y agoGreat resources. It seems we'll see BP monitoring integrated in a mainstream base smartwatch before we'll get optical glucose monitoring.
- privatelypublic 1y agoSmartphones are notorious for not delivering- heck, my fitbit won't even give me an actual wrist temp value. Theres optical ones that can be built in a lab and require profiling to an individual. The most accurate ones are still invasive- just not consumable fungus extract based. Maybe some biomedical company makes a reference design.
- leakycap 1y agoI have used my phone camera to determine blood pressure, but I have yet to see a common consumer device with optical glucose monitoring. I'm suggesting that it will change the world when it is an integrated part of something many/most of us buy and would eventually upgrade to.
- ASalazarMX 1y ago> I have used my phone camera to determine blood pressure You mean heart rate? they cleverly work by flooding your skin with the flash LED, and looking for small differences indicative of a heartbeat. Blood pressure is not something you can image with a consumer camera.
- privatelypublic 1y agoCamera? Yes. Normal illumination? No.
- shreezus 1y agoI believe we will see integrated optical glucose sensors in a popular consumer wearable fairly soon. I don't think they'll be as accurate as blood sensors, however they will be a game-changer for many people (pre-diabetics, or gestational diabetes etc).
- sdpy 1y agoThat would be a game-changer for so many people. We're already getting close, though. Those CGMs like Dexcom don't actually test blood; they check interstitial fluid. There's a 5-15 minute delay, but still way better than finger pricks all day. Non-invasive monitoring is still tricky. There’ve been some interesting attempts—like GlucoWatch back in the early 2000s, which used mild electrical currents, but caused skin irritation and never really caught on. Others have tried optical monitoring, radio waves, ultrasound, and even heat-based sensors. Feels like we’re getting closer, just not quite there yet.
