Abstract
The application describes MEMS transducers comprising a flexible membrane supported at a supporting edge relative to a substrate and further comprising one or more unbound edges. The shape of the unbound edge is selected so that the flexible membrane tends to bend along more than one bend axis in the region of the supporting edge.
