Piezoelectric Actuator for Intra-Cytoplasmic Sperm Injection

Author(s): Andi Sudjana Putra, Sunan Huang, Kok Kiong Tan, Sanjib Kumar Panda, Tong Heng Lee.


While manual ICSI has been able to accomplish artificial fertilization rather satisfactorily, it has also been associated with several drawbacks inherited from its manual manner of operation. Piezo-assisted ICSI is currently gaining attention and preference because of its ability to perform sperm injection in a precise manner, which has significantly improved the result. A number of piezoactuators for this purpose have been proposed. This paper discusses the publications and patents pertaining to this application, as well as a proposed device to further improve the result.
