1. A method for transferring a solid body across a surface of a biological body, the method comprising the steps of:

  • disposing the solid body in a cartridge coupled to a nozzle;

    applying an electrical input to a controllable electromagnetic actuator;

    producing with the electromagnetic actuator a mechanical force corresponding to the electrical input; and

    applying the mechanical force to a reservoir coupled at one end to the nozzle, the mechanical force producing a pressure within the reservoir, a magnitude of the pressure varying with the mechanical force and causing needle-free ejection of a fluid from the reservoir through the nozzle into the cartridge to drive the solid body from the cartridge and into the biological body, the cartridge being separate from the reservoir.
