1. An injection device, comprising:
a needle movable from a retracted configuration to a deployed configuration;
a piston configured to move within a vial;
a motor configured to apply force against the piston; and
a controller coupled to the motor, wherein the controller is configured to:
receive an indication that the injection device is positioned in contact with a user;
after receiving the indication, sending a signal to the motor to apply force against the piston in a first direction, wherein applying force in the first direction causes the needle to move from the retracted configuration to the deployed configuration; and
without requiring any intervention by a user after receiving the indication, and after sending the signal to the motor to apply force against the piston in the first direction, automatically sending a signal to the motor to apply force against the piston in a second direction, wherein applying force in the second direction causes the needle to retract.
