Abstract

Piezoelectric micropumps enable miniaturization in microfluidics for lab-on-a-chip applications such as Organs-on-chips (OoC). However, achieving a steady flow with these micropumps is a significant challenge because of the reciprocating motion of the displacing component. Although dampers are widely preferred for reducing ripples, they are not efficient at low flow rates. Here, we propose a phased-actuation of piezoelectric micropumps connected in parallel and a damper to minimize ripples at low flow rates. We are able to reduce ripples by 80% with our proposed configuration compared to a micropump-only configuration between 10-50 μl/min flow rate range.
