Research on the device of cell medicine microinjection based on piezoelectric actuator

put forward the new cell injection device which constitutesof the piezoelectric actuator tiny flat roof and the electric engine tiny flat roof. Moreover,at the same time advanced makeding use of the piezoelectric chinaware of micro displacement characteristic builduping micro injection pin framework and control system, the piezoelectric micro injection pin that utilizes piezoelectric actuator and its injection system also imposes piezoelectric actuator.the device acquires precision micro injection by making use of at the condition of micro displacement piezoelectric actuator's displacement and the infliction voltage on the piezoelectric actuator hasing linearity relation.
