I have a question about frequencies, not sure if I will word this right but... Are there instances where more than one frequency is used in a crystal to reach a higher peak? If I were to use a lower resonant frequency along with a higher frequency, say at a particular octave/phase angle...would I get any gains being that the second higher signal might not have any loss as it rides along with the first lower wave?
Question rephrased: Can driving the crystal/transducer with multiple frequencies increase the mechanical oscillations? Yes, for example, driving with first and third harmonics will create a triangular-ish wave with a higher amplitude. Even if a higher overall displacement is not achieved, there are instances of higher acceleration and velocity. That being said, it is very rare for transducer to be excited with two frequencies because the potential benefits do not warrant the mechanical design and electrical design complexity. I'll try to do a video on this.
Excellent content yet again, could you please briefly discuss the emerging MEMS technology in a future episode, thankyou.
That's a great topic!

That is a good question to ask.
