Strong electroacoustic effect in ferroelectric liquid crystal cells [article]

Frank Gießelmann, Ingo Dierking, Peter Zugenmaier, Universität Stuttgart, Universität Stuttgart
A strong electroacoustic effect of a ferroelectric liquid crystal cell was observed with a 1 MV/m electric square field in the frequency range from 3 kHz to 30 kHz. The sound emitted can be heared with the naked ear and easily detected with a simple microphone. The electroacoustic effect vanishes in the chiral SA-phase.
