Got it. So it’s not exactly replacing finger-prick tests anytime soon. What about stuff like cortisol or hydration tracking? Feels like that might be …

This is super interesting. I get the idea in theory, but how accurate are these chemical sensors really? Like… can sweat actually reflect blood glucos…

Interesting. So would you say future wearables are more about sensor fusion than better sensors?

Jumping in here — when you say “IMUs need help,” how minimal can that help be? Are we talking full optical systems, or can something dumb and cheap …

Got it. Then what about piezo sensors?They sound way more “well-behaved.” Why aren’t those everywhere in wearables already?

Okay, this is interesting — but I’m still a bit confused.If triboelectric sensors have insanely high voltage, why can’t they just replace normal press…

Got it.So basically: “big power devices = not happening yet,”but “sensor-only wearables = totally becoming battery-free soon,” right?

Damn.So does that mean we can make smartwatches with no battery at all?Like… zero charging forever?

Hey, I just read your post and I gotta ask…Is it actually real that these sensors can run just from body movement without any battery?Like… you just w…

I see. Ultimately, technological advancements that improve usability are crucial. Thank you for the helpful information!

Oh, there’s the weight issue. So how can flexible battery technology and external power be applied? Are there any commercialized examples?

That’s an interesting topic. But what specifically constitutes the biggest obstacle to the power supply issue? Isn’t simply increasing battery capacit…
