In contrast to thermal ink jetting that uses heat to generate fluid drop ejection, MEMS-constructed piezoelectric ink jet printheads use a thin layer of PZT bonded to a silicon diaphragm. The PZT’s morphological response to an electronic signal generates acoustic energy that drives drop formation. Nozzle size determines the metered quantities deposited. We have used this noncontact and nondestructive printing process to immobilize a variety of functional materials while retaining their activity. The MEMS fabrication process increases fluid jetting straightness and opens the operating window for materials with complex rheological properties. We have used this printing process to make patterned thin films of biomolecules, inorganic particles and organic polymers. Fluid formulation is a key parameter that determines the electromechanical jetting success and substrate fluid interactions after printing. We have formulated a variety of inks for the printing of nanomaterials including silver, gold, DNA, peptides, proteins, dendrimers, quantum dots, and carbon nanotubes. After printing dendrimers, inorganic thin films are grown on the organic layer measuring less than 170 nm creating a patterned hybrid composite. These hybrid composites may have utility in finding new materials for electronic components. We have demonstrated the strength and utility of this technique to print electronic components, and further directions will be to integrate these additive processes and couple them to device manufacturing.
