Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Record Performance in Vertically Stacked, Solution‐Processed ZTO Schottky Diodes

Advanced Materials Technologies, EarlyView.
Schottky diodes based on solution processed sustainable zinc—tin–oxide thin films present an eco‐friendly and versatile alternative to conventional CMOS based technologies. Beyond state‐of‐the‐art performance for vertically stacked solution‐based oxide diodes was achieved, including rectification ratios exceeding nine orders of magnitude, and intrinsic

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant

Advanced Materials Technologies, EarlyView.
A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Miniature

, 2018
This thesis investigates a typology of interiors that evoke the sensation of containing the whole world in miniature. It explores the reverie of something being able to expand as you go deeper; that is, something which seems like it is a complete world, or appears larger than it is.
