Microfluidic systems are widely used in various applications, including precise delivery of drugs into organs or tissues. The drug delivery system should have a compact pump with a high flow rate and precise dosage accuracy. In this work, we propose a novel micropump based on an electrochemical actuator that meets these requirements. It contains a glass substrate with three actuators, and a silicon substrate with a channel for a pumped liquid. Side walls of the actuators and channels are made of photoresist SU-8. The pumping is performed peristaltically. The working part of the pump has a size of 3 mm3, which is an order of magnitude smaller in comparison with conventional devices. Compact size ensures ultra-precise dosage of 0.14 nl that is necessary for drug delivery systems. Design and testing procedure are described in detail, and working characteristics are provided.
