Abstract
A one-step sub-micrometer-scale electrohydrodynamic (EHD) inkjet three-dirnensional (3D)-printing technique that is based on the drop-on demand (DOD) operation for which an additional postsintering process is not required is proposed. Both the numerical simulation and the experimental observations proved that nanoscale Joule heating Occurs at the interface between the charged silver nanoparticles (Ag-NPs) because of the high electrical contact resistance during the printing process; this is the reason why an additional postSintering process is not required. Sub-micrometer-scale 3D structures were printed with an above-35 aspect ratio via the use of the proposed printing technique; furthermore, it is evident that the designed 3D structures such as a bridge-like shape can be printed with the use of the proposed printing technique, allowing for the cost-effective fabrication of a 3D touch sensor and an ultrasensitive tihict air flow-rate sensor. It is believed that the proposed one-step printing technique May replace the conventional 3D conductive-structure printing techniques for which a postsintering, process is used 'because of its economic efficiency.
