In the realm of conformal geometry, we give a classification of the Euclideanhypersurfaces that admit a non-trivial conformal infinitesimal variation. Inthe restricted case of conformal variations, such a classification was obtainedby E. Cartan in 1917. The case of infinitesimal isometric variations was doneby U. Sbrana in 1908. In particular, we show that the class of hypersurfacesthat allow a conformal infinitesimal variation is much larger than the oneconsidered by Cartan.
