Shape Memory Alloy-Based Soft Finger with Changeable Bending Length Using Targeted Variable Stiffness.

Soft robotics
This work described a bioinspired soft robotic finger with variable bending length to conform objects with different sizes by means of selectively varying the structural stiffness of its segments. The basic design is a shape memory alloy-based soft a...

A Novel Fabric Muscle Based on Shape Memory Alloy Springs.

Soft robotics
Fabric muscle is important for wearable robots that are soft, compliant, and silent with high contractility and high force. This study presents a novel shape memory alloy (SMA) spring-based fabric muscle (SFM). The SFM is manufactured by bundling SMA...

Continuum Robotic Caterpillar with Wirelessly Powered Shape Memory Alloy Actuators.

Soft robotics
Wireless power transfer (WPT) has the significant potential for soft-bodied continuum robots to extend the operational time limitlessly and reduce weight. However, rigid power receiver coils, widely used in WPT, hinder the continuum deformation of th...

Capsule robot for gut microbiota sampling using shape memory alloy spring.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: Human gut microbiota can provide lifelong health information and even influence mood and behaviour. We currently lack the tools to obtain a microbial sample, directly from the small intestine, without contamination.
