true. a halfbaker who lives with me also suggests that the greater the voltage generated, the larger the weight, so just some kind of weight to voltage conversion tabel needed within. |

As I understand the piezoelectric effect, the crystal would only be able to power anything while the weight was changing. Once the mass has been sitting on the scale long enough to stop moving and thus be read as a valid weight ("settling time" in scale lingo), the crystal's charge will likely have been depleted by the electronics that are trying to measure the voltage in the first place. Probably. Maybe. |

maybe it could charge a tiny battery
whilst the weight is in motion - then
display the weight of the object once
it's stopped. |

You could use quartz crystals for the
heavier things ang nitrogen tri-iodide
for anything weighing less than a gram.
