We report measurements of the bulk flexoelectric coefficient (e1 − e3) of 5CB (4-Cyano-4′-pentylbiphenyl), in the temperature range 20–34 °C, with a relative combined standard uncertainty of 2 %. The chiral flexoelectro-optic method was used with 1 wt % high-twisting-power chiral additive. At 25 °C, (e1 − e3) = 7.10 pC/m with a combined standard uncertainty of 0.14 pC/m
