Multi-axis piezoelectric transducer
Abstract:
A multi-axis transducer is provided. The transducer includes: a stationary member; at least two connecting members and two or more energy-conversion elements disposed on each connecting member. Each connecting member is attached at one location thereof to one of the stationary member or a second connecting member and, in response to a stimuli, is free to move along any of three geometric axes that are perpendicular to each other. Each energy-conversion element operates to convert motion of the connecting member to electrical energy or vice versa. A common geometric plane passes through each of the at least two connecting members and the stationary member, and the two largest dimensions of each connecting member defines a geometric plane that is parallel with the common geometric plane.
