| Abstract | Pyroelectric energy harvesters (PyEHs) have been extensively developed for the energy supply to wireless, lowpower advanced devices. Plenty of experiments show that the voltage-time curves for evaluating pyroelectric devices are alternatively positive and negative, while the fundamental pyroelectric theory gives a positive voltage without the negative portion. Here, this key confliction is addressed by both theoretical and experimental investigation. The voltage-time curves are recorded by three voltmeters with inner resistances of 10 M omega, 150 G omega, and 200 T omega, respectively. Measured output voltages are found to be influenced greatly by the voltmeter's resistance and capacitance, with peak voltages differing by a factor that exceeds 2200. The performance of the PyEH should be characterized by the intrinsic voltage rather than the open-circuit voltage. As a significant conclusion, the resistance and capacitance of voltmeters used should be reported in the literature, thus providing a rationale for comparing the performance of different devices. |
