About NanoMuscle

NanoMuscle Inc., founded on December 31, 1998, was a developer and manufacturer of miniature actuators based on shape memory alloy (SMA) technology. The company was established by high-tech entrepreneur Rod MacGregor, who aimed to commercialize the next wave of significant technological advancements. A notable early backer of the startup was Hasbro, a major toy company, which had plans to incorporate NanoMuscle's technology into its products.

The core of NanoMuscle's business was the production of small, powerful motors that utilized the properties of a nickel-titanium alloy (Nitinol). These actuators functioned like a human muscle, contracting when an electrical current was applied, which caused the Nitinol wire to heat up and change shape. This process allowed the devices to perform linear or rotary motion with significant force relative to their small size and weight. For instance, the NM706-Super actuator, weighing only 1.1 grams, was capable of moving a 70-gram load. The technology was positioned as a lightweight, silent, and solid-state alternative to conventional small motors.

The company targeted a broad range of markets, estimated to be worth billions, including consumer electronics, automotive applications, and toys. Specific uses included powering windows or creating nuanced facial expressions in dolls. The business model focused on manufacturing these actuators at a low cost—reportedly under $1 per unit—to supply to other companies as clients. Following the discontinuation of its original operations, the NanoMuscle product line and brand were acquired by Miga Motor Company (now Miga Robotics), which continues to design, manufacture, and sell these shape memory alloy actuators.
