The Radio Shack piezo, part number 273-073, has been shorted, what, a few days now non-stop. Late last night I disconnected the piezo from the Kiethley picoamp meter and then quickly shorted to piezo. This morning the Kiethley was turned on and allowed to warm up for close to an hour, and then connected to the piezo again. It produced 8 pA, slowly went up to 12 pA, and seems to be slowly oscillating around 10 pA. So it's seems clear that the piezo's, and probably diodes as well, will produce DC current & voltage indefinitely!
That is great news! For now, I will refer to diodes, piezos, electrets, and crystal batteries as Electrets. So here is the way I see it so far, and time will tell for certain: Regardless of how many Electrets are placed in-series, or in-parallel, or how large or small each Electret is, when it has produced DC current long enough the current will decay and settle to ~ 10 pA DC. Yet, this does not mean a larger component will not produce more overall power than a smaller one. This means that when the components are fully exhausted they will produce the same power, but the larger component will produce more initial power. A properly functioning Electret battery should never be allowed to be exhausted to 10 pA. The Electret battery when undisturbed would produce its maximum power, and over time the power will decrease. At such a point the Electret battery should be disconnected/unloaded to allow it to recover again. There could be two Electret components that switch where one is always recovering.
