The development of pumps for precision flow has been taking place in a number of areas (such as bioengineering) for use in the pumping of blood or in the dosage of reagents and medicines.Many of the new principles applied are based on the use of piezoelectric actuators. These actuators offer certain advantages over other traditionally used types, such as greater potential for miniaturization, less noise generation and reduced number of moving parts. Thus, the present project aims to carry out the study of the technical viability of a new configuration of piezoelectric flow pump by means of the elaboration of computational modules, the optimization of parameters and the construction of an experimental bench top prototype to check its functionality. Simultaneously with the technical viability study, two products with potential application in the technology being studied will be researched: water refrigeration systems for processors in high performance microcomputers and blood pumps for applications which involve extracorporeal circulation.
