B. Willing et al., GAS SPECTROMETRY BASED ON PYROELECTRIC THIN-FILM ARRAYS INTEGRATED ONSILICON, Sensors and actuators. A, Physical, 66(1-3), 1998, pp. 109-113
We report on a novel gas spectrometry technique using pyroelectric thi
n-him arrays. The 1 x 50 element arrays of PZT are integrated onto sil
icon using a membrane structure. The experimental characterization of
the pyroelectric elements shows both high voltage and current response
s in defined frequency ranges. Mounting the array as a detector in a c
ommercial spectrometer, we demonstrate its capability of detecting the
infrared absorption curves of gases by the example of CO2. (C) 1998 E
