The potential of piezoelectric, continuously twisted, structurally chiral materials (PCTSCMs) for sensing shear waves is explored. The shear waves to be sensed are supposed to be incident normally on the open face of a PCTSCM slab with hexagonal 6mm reference crystal symmetry. The back face is assumed to be perfectly rigid. After using the quasi-electrostatic approximation, an expression for the potential difference generated across the PCTSCM slab is obtained. Numerical results confirm that the potential difference displays zonal characteristics that depend on the pitch of the PCTSCM and the operating frequency.
