An All‐Fabric Wearable System for Human‐Machine Interaction

Advanced Materials Technologies, EarlyView.
An all‐fabric sensing system enables wearable human–machine interaction through a breathable, stretchable, and scalable design. The all‐fabric capacitive sensor achieves a gauge factor of 2.03 over 72% strain and supports body‐motion tracking, 90.5% hand gesture recognition, and real‐time prosthetic hand control, demonstrating a promising pathway ...

Design and validation of a novel 3D-printed glenohumeral fusion prosthesis for the reconstruction of proximal humerus bone defects: a biomechanical study

Frontiers in Bioengineering and Biotechnology
BackgroundAll available methods for reconstruction after proximal humerus tumor resection have disadvantages, and the optimal reconstruction method remains uncertain. This study aimed to design a novel 3D-printed glenohumeral fusion prosthesis and verify

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Living joint prosthesis with in-situ tissue engineering for real-time and long-term osteoarticular reconstruction

Bioactive Materials
The reconstruction of large osteoarticular defects caused by tumor resection or severe trauma remains a clinical challenge. Current metal prostheses exhibit a lack of osteo-chondrogenic functionality and demonstrate poor integration with host tissues ...

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Composite graft endocarditis: repair with a mechanical prosthesis.

Texas Heart Institute journal, 2004
We report the case of a 64-year-old man who developed a mediastinal pseudoaneurysm due to severe endocarditis, 2 years after aortic root replacement with a prosthetic composite graft containing a mechanical valve. After a short period of stabilization and antibiotic therapy, the patient underwent surgery. The coronary buttons and the sewing ring of the

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
