Non-amplified pyroelectric PVDF sensors on ceramic and PCB substrates

摘要

This paper describes infrared sensing measurements using thin films of the pyroelectric polymer PVDF on inexpensive substrates, without extra amplification of the signal beyond that provided by the usual lock-in amplifier. PVDF is usually used on silcon substrates, which enables integrated circuit amplification close to the singal source. That is not possible with the present substrates, ceramic ceramic (96
