The present invention relates to a biological material interaction platform, a method of making a biological material interaction platform, and uses of a biological material interaction platform. A biological material interaction platform according to the invention comprises a substrate supporting an array of shear piezoelectric material nanomembers configured to support a biological subject and configured such that in use, application of an electric field across at least a part of the array of nanomembers provides local stimulation of the biological subject supported by the array； and/or shear deformation of one or more of the nanomembers by the biological subject supported by the array of shear piezoelectric material nanomembers causes generation of electric potential across at least part of the array. A method of making a biological material interaction platform according to the invention comprises steps of hot pressing a piezoelectric material and a nanostructured template to thereby form an array of shear piezoelectric material nanomembers. Devices according to the invention have a lower effective stiffness surface compared to similar devices not having such a nanostructured material layer, and may accordingly be particularly suitable for interaction with biological subjects.La présente invention concerne une plateforme d'interaction de matériau biologique, un procédé de fabrication d'une plateforme d'interaction de matériau biologique et des utilisations d'une plateforme d'interaction de matériau biologique. Une plateforme d'interaction de matériau biologique selon l'invention comprend un substrat supportant un réseau de nano-éléments de matériau piézoélectrique de cisaillement conçus pour supporter un sujet biologique et conçus de telle sorte que, lors de l'utilisation, l'application d'un champ électrique à travers au moins une partie du réseau de nano-éléments fournit une stimulation locale du sujet biologique supporté par le réseau； et/ou la déformation par
