1. A sensor, comprising:
- a body having a longitudinal recess formed therein and at least one lug extending at least partially across said recess;
a base positioned within said recess and having at least one protrusion extending from said base adjacent said lug; and
a film extending about said base and over said protrusion to form a space between a portion of said base and said film, said film being engaged with said lug and urged at least partially into said space.

Abstract
An acoustic or vibration sensor particularly useful in detecting nano-vibrations includes a body 40 having a generally C-shaped cross-sectional configuration. A base 44 is positioned within the body 40 and has at least one protrusion 68 extending from the base 44 intermediate end portions 48 of the C-shaped cross-section. A film 14 extends about the base 44 and over the protrusion 68 to form a space between a portion of the base 44 and the film 14. The film 14 is engaged with the end portions 48 of the C-shaped cross-section and urged at least partially into the space to place a desired tension on the film.
