In this paper, the development of an automated umbilical cord blood (UCB) collection instrument, comprising of mechanical, electronics and control components, is provided in detail. UCB from the placenta provides a rich source of highly proliferative cells for many clinical uses as it contains rich Hematopoietic Stem Cells (HSCs) which yield many benefits over traditional sources such as the bone...
In this paper, the design of a partially-rotating piezoelectric actuator based on a cylindrical piezoelectric material is presented, with its application in intra-cytoplasmic sperm injection. The principle and dynamic of the proposed system will be discussed, along with its control system. The dynamic of the system is discussed from the fundamental principle of piezoelectricity and structure, resulting...
