Abstract :
We have constructed a portable needle-free drug injection (NFI) device based upon a custom voice-coil linear actuator. Our actuator is optimized to provide high instantaneous force (>200 N) and power (4 kW) while still allowing a total stroke of 25 mm. The actuator is relatively inexpensive, compact, and lightweight, allowing it to serve as the force generator in a portable, reusable, handheld NFI system. The actuator is capable of accelerating liquid drug in quantities of up to 250muL to a speed of more than 200 ms-1. The repeatability of a 50muL volume ejection is better than plusmn1muL
