Abstract

This paper presents the design, fabrication and experimental characterization of a valveless micropump actuated by an ionic-polymer-metal-composite (IPMC) soft actuator. The performance of the IPMC varies over time, therefore on-line iterative feedback tuning (IFT) is used to adaptively tune the PID controller to control the bending deflection of the IPMC to ensure a constant pumping rate. The pump rate is higher at lower frequencies for a given applied voltage to the IPMC. A maximum flow rate of 130 μl/min is achieved at 0.1 Hz.
