We theoretically demonstrate dc and ac electric voltage generation due spinmotive forces originating from domain wall motion and magnetic resonance, respectively, in two-sublattice antiferromagnets. Our theory accounts for the canting between the sublattice magnetizations, the nonadiabatic electron spin dynamics, and the Rashba spin-orbit coupling. We predict that the spinmotive force can of the order of millivolt, several orders larger than their ferromagnetic counterparts. This work suggests a new way to observe and explore the dynamics of antiferromagnetic textures by electrical means.
