The invention pertains to a CellDrum electrode arrangement for measuring mechanical stress, comprising a mechanical holder () and a non-conductive membrane (), whereby the membrane () is at least partially fixed at its circumference to the mechanical holder (), keeping it in place when the membrane () may bend due to forces acting on the membrane (), the mechanical holder () and the membrane () forming a container, whereby the membrane () within the container comprises an cell-membrane compound layer or biological material () adhered to the deformable membranewhich in response to stimulation by an agent may exert mechanical stress to the membrane () such that the membrane bending stage changes whereby the container may be filled with an electrolyte, whereby an electric contact () is arranged allowing to contact said electrolyte when filled into to the container, whereby within a predefined geometry to the fixing of the membrane () an electrode () is arranged, whereby the electrode () is electrically insulated with respect to the electric contact () as well as said electrolyte, whereby mechanical stress due to an agent may be measured as a change in capacitance.
