Fluidic capacitor-based, self-contained and self-powered microfluidic chip

Fluidic capacitor-based, self-contained and self-powered microfluidic chip
Fluidic capacitor-based, self-contained and self-powered microfluidic chip
We describe a fluidic capacitor-based reagent storage and delivery system that is self-contained and self-powered, potentially applicable to highly portable devices for on-site use. Solutions are stored under pressure in polydimethylsiloxane (PDMS) membrane mounted reservoirs (fluidic capacitors) in a charged state, and by releasing the stored pressure, the solution is self-powered to flow and fully discharge within 4 min. The leakage of pressure from the capacitors over time has been reduced by sealing the surface with paraffin wax, where the capacitors remain charged for up to 6 days with 85% of original volume preserved.

Abstract

We describe a fluidic capacitor-based reagent storage and delivery system that is self-contained and self-powered, potentially applicable to highly portable devices for on-site use. Solutions are stored under pressure in polydimethylsiloxane (PDMS) membrane mounted reservoirs (fluidic capacitors) in a charged state, and by releasing the stored pressure, the solution is self-powered to flow and fully discharge within 4 min. The leakage of pressure from the capacitors over time has been reduced by sealing the surface with paraffin wax, where the capacitors remain charged for up to 6 days with 85% of original volume preserved.
