That's an interesting circuit to drive a piezo disk I will be interested in the Arduino circuit so Have joined your channel "Your Link is not working" I wanted to contact you as I am involved in a project. Thanks Bob in the UK

worst explanation methodolgy, seems like confused

my poorly made driver from vevor blew the traces and finging this is a wonderfully simple replacxement

Hi There Iam developing a Medical Ultrasonic cleaner and would like to reach out to your experience for some generator designs.

Hey can I get your help please, I have been trying to learn all of this but it is very hard while being tortured. If you can please help I will help others with your help .

Hi thanks for the video, I was a tech at a company that used 2" PZT-8 bonded to an aluminum plate. I measured to find an equivalent inductance to tune out the piezo capacitance and then could measure R. Now we could setup the amp with a conjugate matching circuit to match C and R of the transducer. We drove it with a 250 watts in a water bath. Our frequency was around 660kHz. My question, we always drove them at the low impedance point. I always wondered why. Is they pattern of the transducer any different between the low and high frequency point?

Hello, have you made a video about drive transducer using si5351? I feel that i've watched that video, but now i dont know where is that video on your channel

are these transducers the same as the ones used for fish finder sonars?

Is it possible to make a 3v to 19kv (1mA max) transformer with a proper piezo transformer? I need it for my night vision project.

Thank you very much! It helps me a lot in my research! I have a question. Since you are measuring d33 in the video, do the applied force have to be in the same direction of the polarization of the PZT?

Great webinar !

Asalam aliekum nice work the world's best teacher thanks sir

You are so smart 😮

Interesting as always. I am always surprised to see the single JFET amplifier used for electret microphones when a cascode arrangement is clearly called for due its reduced Miller capacitance. I guess the small increased cost implications for the added JFET and biasing resistors are the problem...

Great video. Thank you so much. Do you have a video explaining how to increase the efficiency?

My transducer has a huge crack in it , I guess the water wasn't cooling it enough. I'm going to replace the transducer, but surely epoxy resin isn't going to be rigid enough to hold it? The original compound looks like a type of liquid metal, UV light cured stuff as in dental cement?

WELL DONE EXPLANATION.

bro, so can I just plug it to my electrical outlet directly?

Hello Husain, do you one day plan to make a video on ultrasonic cutters? There is a lot of content generally on cleaners online but I find so little on cutters, especially ones like cake and pizza cutter knifes that are bigger, so interested in them, like do they have a stronger transducer or is it just the horn design that makes them cut so efficiently a large cross section

Badger is an idiot. Thanks for the video!

This was useful to extract maximum enjoyment out of a Slinky toy. Thank you

where can i buy that transducer,?

Thank you, sir, I'm watching all of your videos from the website. Hopefully, these may help me with my undergrad research.

what are the real life application of this technology, can this technology be used in respiratory care.

how much does this vibrometer cost and where to buy it? thanks ❤

Thanks man. The transformer was given me a lot of headaches. Still the question is open how to choose the right ferrite and gauge

Slide 14, you say longitudinal sos, whereas you show shear wave sos. What is it?

This is pretty much how electric drum kits work. A piezo picks up the vibrations and you then just trigger a modo signal

I thought I would just Google and see if there’s any videos explaining how to make an ultrasonic cleaner before bed. I get the feeling I’m not going to be sleeping for several hours now. Time to learn more about piezo

How to drive this hesentec rank e transducer?

if i put this ultrasonic sensor on my forearm with same arduino/code setup as in video and i close my finger it will detect the muscle contraction of closing my finger?

The word you were looking for at 3:46 is "transversaly isotropic". Piezoelectrics have to be transversaly isotropic or Orthotripic (PVDF) to be called as such.

Love your videos!! What do you mean by sensor Vs actuator? Can you define both?

Thank you very much for the valuable video. I would like to ask you a question. I made a very similar simulation. I want to compute the impedance of PZT on a frequency range. Unfortunately I'm only managing to getting the real value of the current, but not the imaginary one. As a consequence i can't get the correct imaginary impedance (and also module and phase). Could you please give me an advice? Thank you in advance!

For a project of mine, i need to create high frequency soundwaves through a transducer. My main problem is that I dont have any idea how to accurate supply my transducer with these high frequency signals and still know what frequency I am providing to it. Basically I want to supply frequency range from 1.6MHz to 2.5MHz in steps of 0.1MHz. Is there any way to know beforehand what kind of frequency I am supplying? I can get to 4.05MHz(Max) and I want to accurately delay this to the range of 1.6MHz to 2.5MHz, how to do that?

Thank you for your videos! They help me in my research very much!

Do losses actually increase apart from mechanical resonance? Resonance describes the ability to store energy in the mechanical structure, but energy conservation still applies. Only the reactive power due to the electrode capacitance increases with the voltage, which is necessary for the higher impedance to supply the same power. I would be pleased to hear your view of things.

Hey! I found you recently and I really appreciate the videos! Do you think you could make a video on parametric speakers? Thanks!

How do you calculate dielectric loss tangent? That is important for me to know. Thank you

Thank you very much, this video is very useful. I believe I will loock it throuth several times

Super interesting and did covered "everything" in this seminar. very, very informative. Thanks.

which is the best software for the simulation of Sonotrodes??

Most interesting content!

keep going , great job, i always wait for your videos

Very nice

hello Husain. tnx for webinar. it will be very useful to also have a webinar on importance, design, simulation and applications of boosters!

did si5351 able to shot a single pulse?

I wonder why you never felt it necessary to use the base vector coordinate system for the piezoelectric material in your simulation..

Thanks sir. Please model piezoelectric of humidifier in 2.4 MH
