Examples:
- Each window is sealed under a thin polymer layer, balancing optical clarity with biocompatibility while preserving the ring’s continuous, scratch-resistant exterior. <- they're on the interior of the ring, and I'm assuming if they're polymer, they're not very scratch resistant.
- This flexible board architecture allows the Oura Ring to maintain its circular form as well as distribute heat [...] <- what heat? And how?
- The charging coil runs along the ring’s outer circumference [...] <- scan shows a small coil on the inside, not running along the circumference
- [...] we can easily visualize the deployment channel and insertion mechanism that guide this filament to its precise depth and angle. <- I can't see the insertion mechanism.
- spiral geometry <- the Bluetooth antenna isn't spiral. Nor does it communicate "through the user's skin"?
- miniature microphones (visible as small cylindrical cavities) <- they're rectangular.
But especially nonsense like ”allows the Oura Ring to maintain its circular form as well as distribute heat” is what you get when you RLHF your chat bot for lazy students cheating on homework.

Insulin is incredibly potent and can easily result in life-altering if not fatal consequences at relatively low ratios of the therapeutic dose, so these things need to be dialed in and extremely reliable.
This is an extreme corner of quality/cost/reliability optimization. The delivery mechanism has to be extremely repeatable and reliable, it has to fail in safe ways, but at the same time, it has to be cheap enough to throw away.
Durable pumps are all made with very expensive precision mechanisms, lots of metal and high quality plastic.
Why is the Omnipod available[0] to explore in Voyager, but the Dexcom is not? I'd like to send links to both for my diabetic girlfriend to enjoy, who uses those two particular devices.

PS: Nice company logo btw. ;)
As for pricing, https://news.ycombinator.com/item?id=45392896 had some numbers from 5 months ago. It seems like the kind of thing that you'd want as a nearby service, unless you needed to do continuous inspection (they have some automated conveyor sampling products too, it looks like.) My last company had a few 3d-printed components that would have been interesting to spot check after wear testing, but for a lot of things, the competition for the scan is "open it up with a screwdriver" :-)
In something ring-sized? Maybe for about five minutes, and then the battery dies. (I assume you mean using resistive elements to create heat; heating the actual battery seems like a bad idea.)
Unless the ring is shaped as a heatsink/radiator, I imagine it would eventually get into equilibrium, and you wouldn't feel the heat-flux.
Is it possible that the "coldness" comes from its indirect affect on blood-circulation?
Oura - based in SD.
Dexcomm - based in SD.
Omnipod/Insulet - major R&D hub in SD & TJ.
San Diego does have a bunch of health tech, but it pales in comparison to Boston.
I don't have firm data on this, but colloquially among medical people, San Diego is seen to have more biotech startups than any other metro, including Boston/SF.
Boston has more research, of course, though SD is competitive there as well.
We can disagree about numbers etc, but 'pales' doesn't reflect reality.

One thing I really enjoyed about the analysis was how it really explained the nuance of the technology they sell, and there were always lessons in it for how to tweak the machines on different objects/materials, and how to interpret things, and why certain areas looked the way they did.
For example, on the Omnipod[0], why can't I find an attenuation window to see how much medicine is left inside the reservoir? Is it empty? Is the medicine too low in attenuation to be seen? Is the medicine too similar in attenuation to the outer casing to isolate from it? Could it be isolated if the machine were set up / configured with different settings, and if so, what are the tradeoffs?

Maybe a wearable ultrasound instead?
edit: after a little informal side-searching after posting this, I've learned that people working at Chernobyl, not in the reactor directly, but elsewhere in the sprawling site received anywhere from 1 to 100 CT scans worth of radiation. The firefighters that were on the roof received anywhere from 100 to 1,600 CT scans worth of radiation.
If one is concerned about the potentially damaging effects of radiation, and the relative safety of ultrasound technology springs to mind, then one may be also interested in reading more about the apparently forbidden topic of ultrasound safety studies, if such a person can get past the cognitive dissonance from having been told the consensus opinion on how safe ultrasound is, e.g.:
