Abstract
The invention is concerned with a pressure diaphragm that is composed of a nonmetallic material that has been sculptured by etching a plate to form thick motes, or islands, and a thick rim interconnected by thin sheet material. The thick portions are separated by thin flexures in which the deflection of the diaphragm is concentrated, whereby the deflection yields a high value of electric output per unit pressure.
