WebThe development of microfluidic chip-based cytometers has become an important area due to their advantages of compact size and low cost. Herein, we demonstrate a sheathless microfluidic cytometer which integrates a standing surface acoustic wave (SSAW)-based microdevice capable of 3D particle/cell focusing with a laser-induced fluorescence (LIF) … Web(a) Bonding orientation of the LN-Si stack; (b) conceptual schematic of the device structure where the AWs launched by the IDTs will be amplified or attenuated by the electrons drifting in the Si layer; (c) the SEM of a fabricated prototype with the inset showing its chirped IDT pattern for achieving a wider FBW.
ELECTRONIC FOCUSED ACOUSTIC BEAM SCANNING USING
WebAn IDT and topological PnC were fabricated on a Z-cut LiNbO3 surface by using a standard electron beam lithography and lift-off technique. In order to excite a SAW over a wide frequency range between 2.2 GHz and 2.55 GHz, a chirped IDT was fabricated, as schematically shown in Fig. 2(a), in which the period of the IDT was WebJun 10, 2024 · Different from the known acoustic streaming pattern of an immersed interdigitated transducer (IDT) ( 34 ), at an excitation amplitude above VT, two ASVs will be formed along the two flanks of an IDT inside the oil layer and spin in the opposite direction to the direction of the surface acoustic wave (SAW) propagation. tssm narhe logo
