Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]
, 2017 Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

Electric Impedance Assisted Micropipette Aspiration
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007 Micropipette aspiration is a technique to selectively isolate cells from cell cultures using suction pressure. Cells can selectively be isolated one by one from neighboring cells into the micropipette. This paper presents a novel micropipette aspiration system assisted by an impedance measurement system.
