title: A Lorentz-force actuated autoloading needle-free injector.
abstract: The advantages of delivering injections via needle-free methods are numerous. However, conventional methods for needle-free injection lack sufficient control over depth of penetration and shape of injection. Thus, a needle-free injector was designed, constructed, and tested, using a controllable linear Lorentz-force actuator. This actuator allows rapid control of the injection pressure during injections. Using this device, precise control over delivery parameters can be achieved. The injector design was tested for repeatability and evaluated for depth control using acrylamide gel and dye.
