Drone Payload Release

These prototype devices have been used as drone payload release mechanisms and for protecting drugs in high security medical carts.  They can be made very thin (less than 2 mm) and lightweight (less than 1 ounce) and can use very little energy to actuate.  They can be used across a wide range of voltages, from 3.7 Volts – 30 Volts.  They can be actuated with as little as 5 watts of power and can be made to hold in the actuated state with roughly 15% of the actuation power.
