Abstract
A piezo-electric inkjet printing system includes an array of transducers. The array includes at least a first transducer and a second transducer. The first transducer is coupled to a first foot, and elongates in response to a first stimulus, causing ink to eject from a first ink chamber. The second transducer is coupled to a second foot, and elongates in response to a second stimulus, causing ink to eject from a second ink chamber. The first transducer is mechanically isolated from the second transducer.

A piezo-electric printing system, comprising:
- an array of transducers, including at least a first transducer and a second transducer, wherein the first transducer is coupled to a first foot, and elongates in response to a first stimulus, causing ink to eject from a first ink chamber, and the second transducer is coupled to a second foot, and elongates in response to a second stimulus, causing ink to eject from a second ink chamber, wherein the first transducer is mechanically isolated from the second transducer.
A method of forming a piezo-electric printing system, comprising:
- coupling a first transducer to a first foot, wherein the first transducer elongates in response to a first stimulus, causing ink to eject from a first ink chamber;
- and
- coupling a second transducer to a second foot, wherein the second transducer elongates in response to a second stimulus, causing the ink to eject from a second ink chamber, the first transducer being mechanically isolated from the second transducer.
A method of a piezo-electric printing system, comprising:
- applying a first stimulus to a first transducer to cause ink to eject from a first ink chamber, wherein the first transducer is coupled to a first foot, and the first transducer elongates in response to a first stimulus;
- and
- applying a second stimulus to a second transducer to cause ink to eject from a second ink chamber, wherein the second transducer is coupled to a second foot, and the second transducer elongates in response to a second stimulus, the first transducer being mechanically isolated from the second transducer.
