Abstract (en)

[origin: WO2005098845A1] The flexible membrane (1) comprises at least one thin layer with a plurality of indentations (2) formed therein, wherein bearing points (3) for actuating elements are disposed between said indentations in order to locally deform the membrane. The thus open-worked membrane (1) is more flexible in a cross direction. The open-worked membrane (1) can act as a support for the recording of data, cooperating with a micro-point bi-dimensional network.
