A critical assessment on micro-blowers and pumps for different engineering applications

This review paper presents the status of piezoelectric-based micro-blowers/pumps used in various applications. Many researchers have proposed different models, changes, and advanced technologies of micro-blowers/pumps for improved system efficiency. These devices are used for fulfilling the requirement of controlled and accurate transfer of fluids (air, water, oil, etc.). Various technologies have been developed and implemented to reduce micro-blower size, power consumption, and system efficiency. A few studies have focused on piezoelectric-based micro-blowers/pumps in various applications. The present paper gives a detailed review of the development of piezoelectric based micro-blowers/pumps, their design configurations, and their applications such as electronic cooling, fuel cell, biomedical, chemistry, precision controlling, drug delivery and chemistry applications. The paper also focused on key futures of micro-blowers/pumps such as working principles, construction, and performance parameters. Significant findings and observations have been reported. This review assists researchers and industries who work on piezoelectric-based systems by providing huge information within an article so that they can make systems that are more efficient.
