20110249853 | ACOUSTIC ENERGY TRANSDUCER - Illustrative acoustic transducers are provided. A monolithic semiconductor layer defines a plate, two or more flexible extensions and at least a portion of a support structure. Acoustic pressure transferred to the plate results in tensile strain of the flexible extensions. The flexible extensions exhibit varying electrical characteristics responsive to the tensile strain. An electric signal corresponding to the acoustic pressure can be derived from the varying electrical characteristics and processed for further use. | 10-13-2011 |

20120027236 | ACOUSTIC PRESSURE TRANSDUCER - Acoustic transducer means are provided. A monolithic semiconductor layer defines a plate, a pair of oppositely disposed torsional hinges, a flexible extension and at least a portion of a support structure. Acoustic pressure communicated to the plate results in tensile strain of the flexible extension. The flexible extension provides a varying electrical characteristic responsive to the tensile strain. An electric signal corresponding to the acoustic pressure can be derived from the varying electrical characteristic of the flexible extension. | 02-02-2012 |
