We apply the Lamb wave resonators (LWRs) in microfluidic field, and design a novel MEMS device consisting of 4 LWRs, that can efficiently drive multiple cylindrical vortices and locally enrich the bioparticles in liquid. The acoustic streaming effects in the fluid induced by the LWR is deduced. A numerical simulation method to compute the acoustic streaming effect is presented, and based on which,...
Piezoelectric transducers have been employed in trapping particles and molecules in microfluidic platform. Here we studied the acoustic streaming effect of multiple Lamb wave resonators (LWRs) in liquid. A novel device consisting of 4 LWRs was designed and fabricated. The experiment result demonstrated that the LWR array can efficiently drive multiple cylindrical vortices in liquid and trapped the...
This paper reported a wireless controlled micro-actuator system for rapid heating and mixing of multiple droplets using integrated arrays of micro-fabricated 2.5 GHz solid-mounted thin-film piezoelectric resonators (SMRs) and a millimeter-scale omnidirectional antenna. An equivalent circuit is proposed to analyze the mechanism of the heating, mixing of the SMR, and the wireless communication system...
Techniques that can manipulate micro or macro biomaterials like cells and organisms have been of interest for a wide range of applications from biochemistry to clinical diagnostics and many clever techniques have been developed. However, methods with the ability to directly manipulate nanoscale biomaterials (e.g. proteins or DNAs) are still challenging due to physical limitations like Brownian motions...
Introduction Developing micro/nano scale devices for biosensing applications have triggered a lot interests in recent years. Miniaturizing the transducer size often increases the limit of detections (LOD) of the biosensor which is largely benefited by its high surface to volume ratio. However, fundamental limitations for further improvement of the LOD of micro/nano scale biosensors are the mass transport...
