SONICFLIP: An Integrated Platform for Biofluid Monitoring
Abstract
The work concerns the focused goal of developing technologies to miniaturize microfluidics for wrist-watch scale assays of biofluids such as interstitial fluids and blood. The platform consists of a microfluidic system driven by an array of piezoelectric pillars. This array is then driven by CMOS electronics. This architecture enables the division of manufacturing between IC manufacturers, piezoelectric chip producers, and microfluidic chip producers in a stacked manner that can fit in a wristwatch format. We demonstrate use of projected ultrasonic fields for distributed forces inside microchannels for programmable microfluidics inside plastic and silicon microfluidic structures. The work also demonstrates resonating structures inside microfluidic channels that can manipulate ultrasonic forces around the structures in a controlled manner for particle trapping. We also demonstrate a strategy for sub-5V and sub 5-milliWatt valve using piezoelectric unimorphs connected to the microfluidic chip via magnetically extruded pillars.
