Similarly, if your piezo device requires a larger current the piezoelectric ceramic will only generate a small voltage. This gives you the electrical work output of a single button push. So, if a piezoelectric ceramic is to generate a large voltage it will do so with only a very small current. This is numerically equal to the total amount of mechanical work stored in the internal spring at that instant when the release mechanism lets go.Ĭonvert that value of mechanical work into electrical work units and assume that all the mechanical work is converted into electrical work by the piezo stack. It's max voltage if you set the axis on the bottom of the screen is about 80 Volts. I have an oscilloscope- it's really old though. It will probably be a straight line, or close to it, which starts at zero on the x-axis and ends at the release point distance. So I have the piezo lighter hooked up to a rheostat with one mega ohm resistance, then a 30 kilo ohm resistor and then another resistor of 1 mega ohm. On a piece of graph paper, make a chart with button push distance on the x-axis and measured spring force on the y-axis. Take your measurements all the way up to the push distance point where the spring mechanism finally lets go and releases the hammer inside to strike the piezo stack. a microcontroller) by using a series resistor of a few hundred ohms. Might be always cheaper now to buy the completed capsules than to get the raw piezo.

For sensor usage, ensure that a high mechanical input will not produce a voltage which kills your processing device (e.g. But years ago in manufacturing, the three-tab piezo with a circuit was cheaper in quantity than the two-wire convenient to use piezos. Using a spring force gauge and a ruler, measure the spring force in the igniter as a function of button push distance for a series of different distances. you can put a 100 kOhm resistor across the piezo output, and you will see that the generated voltage is much lower.
