In this study, a polydimethylsiloxane (PDMS) membrane electrolysis micropump activated by a miniaturized wireless power transfer (WPT) system is introduced. The micropump system has total dimensions of 20 × 14 × 8.2 mm3. Combined with a compact WPT system, the micropump enables the delivery of drugs to the treatment area on demand. The WPT system consists of an impedance matching network and a two-stage voltage multiplier. Voltages ranging from 0.8 V to 1.3 V can be generated at different operating distance of 8 cm to 20 cm away from the RF source. The micropump is capable of delivering liquid continuously over a flow ranging from 0.11 µL/min to 4.84 µL/min. This micropump demonstrates a maximum cumulative released drug volume of up to 100.8 µL and was able to produce a pressure that is higher than the intraocular pressure. The results can be used for the study of age-related macular degeneration, diabetic retinopathy, and other ophthalmic diseases.
