Multi-Purpose Artificial Muscle and Sensor Array for Untethered Soft Robots

Completed TRL 3 (started at 2, targeting 3)

Description

“Soft” machines and electronics contain little or no rigid material and remain functional under large elastic deformation. Because they are soft, lightweight, impact resistant, and collapsible, these technologies have the potential to revolutionize robotics for human-machine interaction and space exploration. In this project, my research team and I will accelerate the application of soft machines to space robotics by introducing a “soft robotic tissue” composite embedded with soft elastic sensors, circuit wiring, rigidity-tunable elements, and actuators. These general-purpose elastic films will be millimeters thick and cover a large area. Because the films are soft and stretchable, they can conform to any shape or volume without exerting mechanical resistance. When integrated into clothing, soft robotics, or collapsible structure, the elastic composites can function as “artificial” skin, nervous tissue, or muscle. Potential applications range from strain, pressure, and curvature sensing for shape and contact detection to compact actuators that enable mobility and manipulation without reliance on bulky motors, transmission systems, or pneumatic hardware.

How to get involved

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
