Key Points

The study aims to develop a compact and efficient valveless micropump suitable for medical implants.
Design and prototype a piezoelectric valveless micropump
Implement a nested rectification structure
Test the micropump for low-power operation and backflow suppression
The micropump shows effective backflow suppression
Power consumption is significantly reduced
Miniaturization is achieved without sacrificing performance

Implication

A novel micropump design demonstrates effective backflow suppression in implantable devices, indicating improved efficiency.

Abstract

The field of implantable medical devices imposes stringent requirements on piezoelectric micropumps, particularly in terms of low-power operation, miniaturization, and backflow suppression. This study proposes a novel valveless piezoelectric micropump...
