I want to set up a piezoelectric crystal and an analog meter to measure the voltage when the crystal has an excitation. I think the voltage out would be very low, possible one millivolt. I also assume that it would be AC voltage, since the crystal is oscillating @100Khz.
I'd only want to use just these two components and avoid using a preamp, battery, etc and just use the voltage generated by the crystal.
My question is where can I get an analog panel meter that would work for this application or how could I measure this without an external power source. If itís not possible, I'd also like to know this.
