We show that for any convex surface in a contact –manifold, there exists a metric on and a neighbourhood contact isotopic to with the contact structure given by where is an eigenfunction of the Laplacian on and is the Hodge star from the metric on . This answers a question posed by Komendarczyk [Trans. Amer. Math. Soc. 358 (2006) 2399–2413].
