摘要： Doped glass scintillators and methods of fabricating the same are provided. Doped glass scintillators can be fabricated by a stereolithography process, and doping can be carried out before the green body composite formation so that homogeneity of the dopant is improved. The structures retain an amorphous structure through the fabrication process, and the vacuum sintering process assists with keeping the dopants in their luminescence-producing oxidation state.

摘要： Biosensors capable of detecting certain biomarkers (e.g., platelet-derived growth factor-BB (PDGF-BB)), as well as methods of fabricating the same and methods of using the same, are provided. The biosensors can be disposable and/or label-free.

摘要： Ultra-reconfigurable reflectarrays using vanadium dioxide (VO2) are provided, as well as methods of fabricating and using the same. The ultra-reconfigurable reflectarrays operate based on the unique phase-change properties of VO2, by including a heating element configured to heat desired areas of a VO2 layer/reflector, such that the VO2 reflector/layer can be reconfigured to have a desired pattern heated (and therefore changed to a conducting state) at a given time, with a good spatial resolution of the desired pattern.

摘要： The subject invention is concerned with systems and methods advantageously applying finite element analysis to establish design rules for a highly sensitive piezo-resistive pressure sensor with an output that is high enough to be detectable by simple and inexpensive circuits and therefore ensure wearability. Four frequently reported micro-feature shapes in micro-patterned piezo-resistive sensors are provided, where the micro-dome and micro-pyramid yield the highest sensitivity. Investigations of different conductivity values of micro-patterned elastomers show that coating the elastomer with a conductive material (e.g., a metallic coating) leads to higher current response when compared to composited conductive elastomers. Advantageous geometric parameters and spatial configurations of micro-pyramid design of piezo-resistive sensors are provided. Results show that an enhanced sensitivity and higher current output can be achieved by a lower spatial density configuration of three micro-features per millimeter length, a smaller feature size of around 100 μm, and a 60-50 degrees pyramid angle.
