Testing the piezoelectric properties of Quartz Crystals

Click For Summary

Discussion Overview

The discussion revolves around an experiment conducted by a participant named Jon, who is testing the piezoelectric properties of Quartz Crystals. Jon seeks advice on the appropriate force to apply for generating voltage and the setup of his experiment.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • Jon inquires about the type of force needed to produce voltage in Quartz Crystals and whether a compressive force applied with clamps is suitable.
  • One participant suggests that a repeating force may be more effective and recommends gluing the piezo crystal to a small speaker for better results.
  • Another participant mentions the possibility of using a piezo element from a disassembled cheap microphone as an alternative attachment method.

Areas of Agreement / Disagreement

There is no consensus on the best method for applying force or the optimal experimental setup, as participants offer different suggestions without resolving the question posed by Jon.

Contextual Notes

Participants do not clarify the specific types of forces or conditions under which voltage is produced in Quartz Crystals, leaving some assumptions unaddressed.

Hello :)

I am Jon and I am conducting an experiment with Quartz Crystals to test their piezoelectric properties. I wanted to ask you a question about my experiment set up.

Which type of force is required to be applied for voltage to be produced? Could I apply a compressive force with clamps on one end of the crystal, and wrap a long piece of copper wire on its other end so to measure the voltage produced.

Could you please advise me if I am carrying out the experiment correctly? What kind of a force do we have to apply to Quartz Crystals for a voltage to be produced?

Please advise me on my experiment set up.

Thank you very much!
Jon
