摘要：
A microneedle applicator system comprising an applicator and a controller. The applicator comprises an electromechanical actuator arranged in an outer housing to apply a microneedle module via a supporting body onto skin. The electromechanical actuator is arranged to displace the supporting body between a first position inside the outer housing, and a second position substantially in line with an opening in the housing or outside the housing. The controller is arranged to control a velocity of the actuator and/or a pressure force of the actuator by regulating the power that is supplied to the actuator. The controller comprises switching circuitry for switching the power supplied to the actuator on and off, and an integrated circuit arranged to generate a pulse width modulated signal and to control the switching circuitry by setting or adjusting a duty cycle of the pulse width modulated signal.
