Wigner researchers P. Salamon, M. Mathe, and A. Jákli from the Complex Fluids Department have published a new publication in Advanced Science titled “Shear-Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals.” In this study, the team quantitatively determined the shear-mode direct piezoelectric coupling constants of the archetypic ferroelectric nematic compounds RM734 and DIO using periodic shear-induced electric current and oscillatory rheology measurements. The results provide new insight into the direct piezoelectric response of liquid ferroelectric nematics and propose a physical mechanism based on flow alignment of ferroelectric polarization.
