Boosting Resonant Sensing in Fluids: A Surprising Discovery
Sri Harsha Paladugu, Kaustav Roy, Anuj Ashok +3
Micro-mechanical resonators are widely used in modern sensing technology due to their high quality-factor (Q), enabling sensitive detection of various stimuli. However, the perform…
PMUT-Powered Photoacoustic Detection: Revolutionizing Microfluidic Concentration Measurements
Kaustav Roy, Akshay Kumar, Vijayendra Shastri +6
This report introduces a novel optofluidic platform based on piezo-MEMS technology, capable of identifying subtle variations in the fluid concentration. The system utilizes piezoel…
Thin-film PMUTs: A Review of 40 Years of Research
Kaustav Roy, Joshua En-Yuan Lee, Chengkuo Lee
A concise review on the thin-film PMUTs, which has been one of the rather important research topics amongst microultrasound experts is being reported. It has been rigorously survey…
