Threadlike motor uses sliding fibers to drive flexible robotic devices without gears
Researchers from EPFL's Soft Transducers Laboratory have developed FiberMotor, a threadlike motor that converts electrical energy into motion through the sliding of concentric fibers. This gearless design enables flexible, bidirectional movement, making it suitable for soft robotic applications. The motor's small size and lightweight construction allow for integration into smart textiles and wearable devices, with potential uses in assistive robotics and haptic systems.

opposite the direction in which the FiberMotor is driven, the device's fibers simply slide past each other rather than locking up. Strength in numbers In laboratory demonstrations, individual FiberMotors could support stationary loads equivalent to roughly 75 grams (2.6 ounces). When bundled together, four motors generated enough force to lift a 46-gram (1.6-ounce) chocolate bar and flex a tendon-driven robotic fing
