Piezoelectric resonance - would this work?

Piezoelectric resonance - would this work?

Piezoelectric resonance - would this work?

(OP)
Hi all,

I was hoping you could help me. I'm designing a system for aeroponics. Aeroponics is growing plants without the use of soil by coating the roots in a fine nutrient-enriched mist. The mist is created by a piezoelectric transducer sitting in nutrient-water vibrating at about 2MHz.

I had the idea to build a system with several plants, each with a bowl of nutrient-water by the roots, with a piezoelectric crystal with a 2MHz resonant frequency sitting in each bowl, then generating a 2MHz electromagnetic field to cause the crystals to vibrate in resonance to make the mist.

Would this work? Can I make the crystals vibrate using just wireless electromagnetism? As far as I understand, it should work in theory, but I haven't tried anything like this before. My technical understanding is very poor, so I was wondering if there's anything important I haven't thought of.

Warmest thanks,
Balatro

In theory, yes, but practically, you'd probably need to dump enough RF to cook your plants, and or destroy any radio/TV reception on your block.

Just a side note- there are off-the-shelf ultrasonic humidifiers available. They work quite well but tend to leave a fine layer of dust on everything if you do not use purified water in them.

If you want to have more fun, try growing the plants in a 20 KHZ sound environment.
