Acoustic pressure transducer |
摘要 |
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. |
