The design is built around a Lorentz-force actuator — a small, powerful magnet surrounded by a coil of wire attached to a piston inside a drug ampoule. When current is applied, it interacts with ...

The spectrum extends from simple low-energy drive components to ultrasonic transducers through to ultra-fast actuators ... linear motors can be developed which can provide even force and speed ...

The device uses a Lorentz-force actuator to create an adjustable high-pressure jet that is ejected out of a nozzle as wide as a mosquito's proboscis, penetrating the skin to deliver highly ...
