Smart Material Fabrics
NiTi smart materials are manufactured in bulk as wire. The wire drawing process is a great contributor to creating the bulk motion in the SMA for actuators. Also, for historic reasons including medical uses, NiTi wire is significantly more accessible than other forms of the materials. Deft Dynamics modified traditional weaving equipment and discovered an…

Braided SMA Actuator Patent Granted
One of the great obstacles to designing shape memory alloy devices is their low movement (strain), which for a straight wire is only 4-8% of the wire length. This invention uses an insulated, braided NiTi to increase the strain (up to 50% of the actuator length) and multiply the force, while providing airflow to cool…

Smart Material Actuators
Shape Memory Alloys (SMAs) are materials that create linear motion from heat or electrical inputs. The electro-magnetic motor has moved industry and automation for over a century, yet modern robotic machines are reaching the fundamental limits of its ability as mechanical systems increase in complexity while decreasing in size. SMA actuators have benefits of extraordinary…
