What are the meanings “microphonic effect” or “acceleration response” as used for pyroelectric detectors?”
All pyroelectric materials are always also piezoelectric. Therefore the pyroelectric chip in the detector reacts on impact sound or airborne sound like a microphone or an acceleration sensor. This behavior is known as the microphonic effect or acceleration response, sometimes also as microphonic noise. This disturbing effect can be compensated for very well by an InfraTec patented pyroelectric chip mounting (so called low-micro technology).
