This dissertation reports the development of resistor-based electronic devices fabricated using novel approaches to inkjet printing. The first component of this dissertation involves the development of resistor-based devices using particle-free inks comprised of AgNO3 and ethylene glycol (EG) with low-pressure Ar plasma to form metallic structures. The AgNO3 concentration was selected to produce Ag structures with sheet resistances between 105 and 101 Ω/□ depending on plasma duration and the EG solvent type used in the ink. To investigate the relationships between ink composition, plasma parameters and device performance, strain gauges and temperature sensors were printed from inks that use one of three forms of EG, differing in their vapor pressure. For the strain gauges, the gauge factor (GF) depends on plasma duration and ink solvent. For each solvent, the GF decreases with increasing plasma duration. Additionally, the GF exhibited a strong dependence on the vapor pressure of the solvent with the highest GFs associated with the lowest vapor pressure. Material analysis revealed strong connections between porosity and ink solvent, establishing a physical basis linking ink solvent to GF. The temperature coefficient of resistance (TCR) for the temperature sensors was generally found to be insensitive to plasma exposure time but strongly dependent on ink solvent. The highest TCR values were associated with the ink having the highest vapor pressure solvent and thus the lowest porosity.The second component of this dissertation involves the development of reactive inkjet (RIJ) printing for acetic acid-based electrochemical sintering of screen-printed Zn devices in order to control electrical resistance during the sintering step. Sheet resistances range from 2x105 to 0.5 Ω/□ depending on drop spacing and number of print passes. SEM images show that cold welding between Zn particles increases with increasing print passes, consistent with sheet resistance measurements. Zn microheaters made using the RIJ process compare favorably to conventional microheaters. The RIJ process enables the fabrication of the resistor and capacitor in a resistor-capacitor (RC) filter from a single Zn layer. The corner frequency varies from ~7 kHz to ~1MHz as determined by the printing parameters used to form the resistor.
