Switchable gas and liquid release and delivery devices, systems, and methods

A drug delivery device, comprising:

• one or more cartridges, each including one or more chambers containing one or more substances;
• a housing including one or more transporting channels, a compartment to hold the one or more cartridges, and an opening to allow one or more actuator-selected substances to form as a drug to dispense to an outer environment from the device;
• and
• one or more actuator switches operable to move between an open position and a closed position based on an applied signal to selectively control release of at least one substance to be delivered out of the device to the outer environment to produce the drug,
• wherein at least one actuator switch of the one or more actuator switches includes magnetically latchable gating structures including a first magnetic component and a second magnetic component that are coupled in the closed position and uncoupled in the open position, wherein:
• the first magnetic component includes a solenoid comprising a solenoid core having a substantially square-loop magnetization loop material, and
• the second magnetic component is structured to bend or change its translational position upon a change in magnetic field from the solenoid core to actuate the opening or closing of the at least one actuator switch.
