Air-coupled ultrasound using broadband shock waves from piezoelectric spark igniters
K. G. Scheuer, R. G. DeCorby
We used an optomechanical sensor to study the ultrasound generated by manually operated piezoelectric spark igniters. These low-energy sparks produce short-duration acoustic shock-…

Ultrasonic spectroscopy of sessile droplets coupled to optomechanical sensors
Kyle G. Scheuer, Franz B. Romero, Graham J. Hornig +1
We describe a system for interrogating the acoustic properties of sub-nanoliter liquid samples within an open microfluidics platform. Sessile droplets were deposited onto integrate…
