Abstract
Applicators and methods for dispensing material are disclosed. The applicator includes a syringe defining an inlet, and outlet, a chamber extending from the inlet to the outlet, a plunger disposed within the chamber, and a piston attached to the plunger, where the piston is configured to move the plunger through the chamber. The applicator also includes an actuation mechanism configured to linearly translate the piston through the chamber so as to dispense material through the outlet, a sensor attached to the plunger, where the sensor is configured to sense a linear movement of the plunger, and a controller configured to adjust operation of the actuation mechanism based on the linear movement sensed by the sensor such that the piston repeatedly dispenses a predetermined amount of the material from the outlet of the syringe over a plurality of dispense cycles.
