The Nano-Morphodynamic muscle strand technology (NMD) is a versatile family of devices for HDRM and custom geometry actuators that do not use any moving parts and are only activated via resistive current or heat (stimulus). These devices have extensive flight heritage since 2013 on dozens of CubeSat missions, and have duty cycles regularly into thousands of iterations, actually proven by empirical data. NMD muscle strands have two position settings, customizable upon manufacturing, with custom deploy strength. They have a slow, steady and gradual movement, which drastically reduces wobbling and rotation feedback, while permanently maintaining a tense position once current or heat is no longer applied. Stimulus can be reapplied to reset position should the device be moved out of position.
