Abstract Scope |
The primary objective of this work focused on analyzing the parameters that affect the resolution of direct ink writing of miniaturized RFID tags for wireless temperature sensing at high temperatures. The inks were made by dispersing the electroceramic particles of size < 7 µm in various organic vehicles. Different volume loadings of the electroceramic particles were evaluated to maximize the solid loadings to achieve high density after post-processing. The parameters that affect the process such as viscosity, wettability, print rate, and particle size were evaluated. Several microarchitectures with feature size ranging from 50 – 250 µm were deposited on different substrates including ceramics to demonstrate the capability of the process. The patterned ceramic substrates were sintered at temperatures >1000oC for further characterization. A suite of characterization was performed by particle size analyzer, rheometer, contact angle measurement, SEM, XRD, and impedance spectroscopy. |
