Research Highlight


Schematic representation of the process of adsorption of water vapor on the Lab-on-a-crystal. The process is probed on the macro-, micro-, and nano-scales.

Scientific Achievement  

Demonstrated a novel platform to correlate optical, electrical, gravimetric, and viscoelastic properties of polymer films under controlled environment.

Significance and Impact

This new platform enables high-throughput multifunctional materials characterization on a continuous scale (macro-to-nanoscale).

Research Details

– Modified a quartz crystal microbalance to enable electrical and optical measurements – Designed a specialized 3D printable cell for multimodal testing – Demonstrated simultaneous acquisition of multiple measurements on the same film – Used machine learning tools to correlate the different properties of a thin film   E.
