I have a question about calculating the power generated by a pyroelectric
material under thermal excitation.

To keep the math simple, let's say I have a 10cm X 10cm material of a PVDF
material with p=25uC/m**2.K which is heated to 40 deg C above its "null" temp
(temp at which zero pyroelectric effect is observed).

By my reckoning such a sheet then generates a charge of + and - 10microColombs
on each electrical contact.

(10uC = .1m X .1m X 40 deg K X 25uC/m**2.K)

Now my question is, if the material is held at that temperature, how much
power (Volts * Current (DC)) is available between the contacts?

Pls explain how I might proceed.
