Chiragdubey Posted September 21, 2015 Share Posted September 21, 2015 Hey, guys. Right, I have a dilemma regarding this matter. I need the piezoelectric actuator to vibrate at high frequency. What kind of power source should I be looking at? The application is for something compact.As far as my knowledge goes, DC will move it just once, but AC will give it a vibration. Is that the case? What other inputs can you give me? Thank you! Link to comment Share on other sites More sharing options...
Sensei Posted September 23, 2015 Share Posted September 23, 2015 Sounds like you would need oscillator https://en.wikipedia.org/wiki/Electronic_oscillator or multivibrator https://en.wikipedia.org/wiki/Multivibrator Start from making multivibrator on breadboard like in figure 1 in above link. Connect 2 LEDs to see how they turn on/off light. Get familiar with how capacitance and resistance changes delays of blinking light. Then move further from this setup.

Externet Posted September 25, 2015 Share Posted September 25, 2015 "high frequency" means nothing. What is the frequency you want the piezoelectric element to vibrate ? Will you apply alternating voltage to it or will you apply alternating motion to it ? Link to comment Share on other sites More sharing options...
