Abstract
This chapter presents the design and testing of a flexure-based microinjector with constant force output dedicated to biological cell micromanipulation. The microinjector offers a constant force without adopting a force controller. The motion control is sufficient to provide a constant output force, that simplifies the system design procedure. The injector is actuated by a piezoelectric actuator via a displacement amplifier. Analytical models of the mechanism are established and verified by conducting simulation study with finite element analysis (FEA) . A prototype device is fabricated by 3D printing process for experimental study. The feasibility of the developed constant-force injector for biological cell micromanipulation is verified by experimental studies.
