This study presents the development of a piezo-actuated fluid delivery system designed for use in both terrestrial and space applications, including environments with varying gravity conditions. The key innovation of this system lies in its piezoelectric actuator, which can achieve a minimum stroke of 100-400 nanometers, providing highly precise fluid delivery. The actuator drives a pusher, enabling the precise movement of fluid with exceptional accuracy. In addition to its precision, the actuator can operate at speeds of up to 171 mm/s, allowing fluid to be delivered at various velocities, depending on the diameter of the barrel and nozzle. The actuator can be driven at two frequencies: low and ultrasonic, further enhancing the versatility of the system. This fluid delivery system holds significant potential in medical applications, particularly for mixing drugs in precise volumes or delivering small quantities of fluid over extended periods, as required in certain medical treatments. It is especially useful in therapies such as chemotherapy, where controlled and precise drug delivery is crucial, as well as in other medical treatments that require careful administration of fluids. The combination of high precision and variable speed makes this system ideal for applications demanding careful control of fluid delivery, even in challenging gravitational environments.
