What would you like to invent?

[Bryn]

I know there's a fair share of budding inventors here that build things for fun but, for those that actually want to take this sort of thing more seriously and hope to make things better for everyone or simply to revolutionise basic concepts, what would you create?

For me, I would invent an alternative for taking blood pressure, particularly one that doesn't have to squeeze one's arm to take it (as to me causes discomfort, and at times can give inaccurate readings even from the patient making slight motion).

I've recently thought of it of having a large ring-like design where it can adjust to the circumference of the patient's upper arm like for the basic cuff but instead of having it squeeze the arm to get the readings (and the pulse included), I'd have it "read" the systolic and diastolic levels instead, although that may sound impractical. I'd think more thought would have to be put on that should it be a successful product...

So, what about you?

A genuine solution to climate change that doesn't involve massive compromises from everyone and so actually happens.

A bit like how we fixed the hole in the ozone layer because we found refigerants that were better than freon in nearly every respect so there wasn't that much pushback against them.

We already have that.  Emo-grass cuts itself.

There are already some companies working on "cuffless" blood pressure sensors. Like this one:

https://valencell.com/our-product/

Note that this isn't FDA-approved yet and is not formally clinically-proven, so that's not a replacement, but could be interesting already if you need to take it very frequently.

They use photoplethysmography, like pulse oximeters, with some dedicated algorithms.

A camera/microphone that recognises deception (in the same manner as facial recognition, voice recognition, gait recognition, etc)

Essentially a modern lie detector, but without the intrusiveness of breath rate and galvanic skin sensors.  Should be compatible with existing CCTV infrastructure.  Should be compatible with smartphone cameras/microphones.

That's interesting... hope it goes get approved and then go on sale 👍

On the contrary: triple glazing performs worse.

"Not for sale in the USA"....from a company based in the USA...."freest" country in the world strikes again! 

That gives me some ideas...that would probably get me put "on the list" if I were to mention them in public...

To learn the US Patent application process,

Read "Patent it yourself" by our old friend David Pressman

https://www.amazon.com/Patent-Yourself-Step-Step-Filing/dp/1413329977

Expect about 5 yrs and $5..10K per patent.

Getting a patent liscenced or enforced is a different issue

Well that makes sense. "Blood pressure monitors" fall into the medical device category, so need to be FDA-approved before one can sell them in the US.
They probably could still sell them as a gadget, but if they intend to market them as true blood pressure monitors, that would ruin their marketing. They could even get in trouble for that, as even if not sold as blood pressure monitors, the fact they provide blood pressure measurements could mislead customers. So, yeah.
