Hon Lik, a Chinese pharmacist, is widely credited[8][9][10] with the invention of the first generation electronic cigarette.[11] In 2000, he came up with the idea of using a piezoelectric ultrasound-emitting element to vaporize a pressurized jet of liquid containing nicotine diluted in a propylene glycol solution.[12] This design produces a smoke-like vapour that can be inhaled and provides a vehicle for nicotine delivery into the bloodstream via the lungs. He also proposed using propylene glycol to dilute nicotine and placing it in a disposable plastic cartridge which serves as a liquid reservoir and mouthpiece. These inventions are the basis of the present-day electronic cigarettes.

OK, so does anyone know about the piezoelectric ultrasound emitting element that was developed in 2000? Did the thing have wicks? Did it gunk up?

Is it an error? They all have coils that I know of.

We've bantered about ultrasonic atomizers for quite a while in the modder's forum. I was surprised to hear the original e-cig from 2000 was ultrasonic.
Yes, I didn't know that either. I almost bought one of the small personal misting "steamers" to take it apart. Then I realized I probably wouldn't know what all the parts did once I dismantled the device :D

I had intended to look into this, but something I read cooled my enthusiasm. Basically they were saying any impurities in the juice would be in the mist. So I expect that they gunked up less because you are inhaling what gets left behind on the heating coil. Including microbes that would be killed by a coil.

Still I would like to see more information on the ultrasonic method.

Interesting...many of the cool mist humidifiers use piezoelectrics, but I suppose the impurities/contamination is why they come with blue lights for the reservoir...

I doubt that the blue light does anything more than look pretty.
I think the blue light is supposed to kill germs, but I have no idea if it really does. But if it doesn't do anything, then there should be a way to miniaturize the components for vaping. That, of course, would take someone much more clever than myself :D

Yeah that kind of thing is part of the question. Since:

A) The 1st modern e-cig (in 2000 no less) was ultrasonic
B) They are all coil driven now

It does beg the question. But I think it's as much a factor of part cost too. You wouldn't want all cartos costing $30.00 each or whatever (unless it lasted forever).

I'm not convinced that the coil sterilizes all juice. Just the airflow through an atty/caro could be filled with whatever. And PG is anti-bacterial. So.... who knows.

I also wonder what's left behind on the coil. Then again, I wonder "where the silica goes" too....;)

It seems to me plenty of people are willing to pay over $200 for a Provari or a Reo or another mod. And then there are atty devices that cost close to $100 or over. I would guess that there is a market for another "high dollar" device for juice delivery.

I'm not as concerned about germs in general, and was raised in a "pound of dirt" kind of way :) It also seems that any method/device will have some sort of drawback or disadvantage. An ultrasonic device seems like it would have a distinct advantage of not burning the juice, which IMO would be a huge plus for many vapers (especially new ones). The elimination of wicking materials would also be a selling point for many people on this forum from what I've read.:2c:

It would be interesting to see if eliquid would vaporize in one of those humidifiers. We need some Dr. Frankensteins to play with this.
If the cool mist humidifiers can create a mist with essential oils, then ejuice can be nebulized/misted as well. It seems that adjusting the frequency of the piezoelectric components would do it. Many inkjet printers also work on the piezoelectric principle. But I do agree, we need a Dr. Vapenstein to whip something up for us. I volunteer to test it :)

While searching in vain for more information on ultrasonic cigarettes I ran across a portable ultrasonic device used for essential oils. Which I have ordered by the way. They talked about the small holes created by lasers causing a finer mist. This got me thinking. Perhaps part of the reason that everything is now coils is that ultrasonics create more of a mist rather than vapor. What coils deliver might be closer to smoke than ultrasonics.

Any chance you'd like to share a link or two? :D
