Claim Text:
1. A single-axis accelerometer, comprising: a housing defining a sleeve having a longitudinal axis; an object having a mass disposed in said sleeve for sliding movement therein in a direction aligned with said longitudinal axis; a first piezoelectric strip attached to a first side of said object and attached to said housing, said first piezoelectric strip longitudinally aligned with said longitudinal axis, said first piezoelectric strip including a first strip of a piezoelectric material with carbon nanotubes substantially aligned along a length of said first strip; a second piezoelectric strip attached to a second side of said object and attached to said housing, said second side opposing said first side, said second piezoelectric strip longitudinally aligned with said longitudinal axis, said second piezoelectric strip including a second strip of said piezoelectric material with carbon nanotubes substantially aligned along a length of said second strip; and a voltage sensor electrically coupled to at least one of said first piezoelectric strip and said second piezoelectric strip.
