“…Recently, surface acoustic wave (SAW) sensors [14][15][16] have been extensively used in liquid [17,18] and gas [19][20][21] detection because of their low cost, high precision, miniatur-ization, and compatibility with semiconductor technology. The SAW sensor consists of a sensing film and a conversion element (SAW resonator or delay line).…”

In this paper, surface acoustic wave (SAW) sensors containing porous graphene/PVDF (polyvinylidene fluoride) molecularly imprinted sensitive membrane for DMMP gas detection were investigated. A 433 MHz ST-cut quartz SAW resonator was used to convert gas concentration changes into frequency shifts by the sensors. The porous graphene/PVDF film was fabricated on the sensor’s surface by using the tape-casting method. DMMP molecules were adsorbed on the porous structure sensing film prepared by the 2-step method to achieve the specific recognition effect. The sensitivity of the sensor could reach −1.407 kHz·ppm−1. The response time and recovery time of the SAW sensor with porous graphene/PVDF sensing membrane were about 4.5 s and 5.8 s at the concentration of 10 ppm, respectively. The sensor has good anti-interference ability to most gases in the air.

“…In addition, surface acoustic waves (SAW) have also attracted wide attention 31,32 , due to its attributes, including high energy confinement waves propagating along the surface of the substrate, efficient fluid-structure coupling, and being clean and non-polluting 31,33,34 . Consequently, SAW-based microfluidics have been widely used in microdroplet manipulation including splitting 10,11 , merging 14 , sorting 16,17 , capturing and releasing 20 and other applications such as fluid and particle manipulation 31,34,35 , chemical synthesis, and atomization drug delivery 33,[36][37][38][39][40][41] .…”

We demonstrate a novel microdroplets generation method by using focused surface acoustic waves (FSAW). The method differs from previous work in the mechanism and the geometry structure of the chip, which is depend on FSAW rather than flow shearing. The acoustic radiation force arising from FSAW acts on the oil-water interface, breaking up the water into microdroplets whose size can be controlled by tuning the driving voltage and frequency of FSAW. This approach overcomes the limitation of microchannel structure and capillary number of the traditional microfluidic droplets formation methods, which enables a fully electrical control of microdroplets size, with a good uniformity. Further, the FSAWinduced microdroplets are used as templates to prepare microgels with uniform size, offering a new platform for the design and synthesis of monodispersed functional microspheres.
