Streamlined Inkjet‐Printing of Stretchable Organic Photodetectors

Advanced Materials Technologies, EarlyView.
This work introduces stretchable photodetectors fully inkjet‐printed on stretchable substrates. It is demonstrated that printed stiff platforms effectively decouple strain from the stretched substrate and serve as a chemically resistant and mechanically rigid platform.

Design, Implementation and Evaluation of a Variable Stiffness Transradial Hand Prosthesis [PDF]

arXiv, 2019
We present the design, implementation, and experimental evaluation of a low-cost, customizable, easy-to-use transradial hand prosthesis capable of adapting its compliance. Variable stiffness actuation (VSA) of the prosthesis is based on antagonistically arranged tendons coupled to nonlinear springs driven through a Bowden cable-based power transmission.

Semi-autonomous Prosthesis Control Using Minimal Depth Information and Vibrotactile Feedback [PDF]

arXiv, 2022
A semi-autonomous prosthesis control based on computer vision can be used to improve performance while decreasing the cognitive burden, especially when using advanced systems with multiple functions. However, a drawback of this approach is that it relies on the complex processing of a significant amount of data (e.g., a point cloud provided by a depth ...

High‐Conductivity, Self‐Healing, and Adhesive Ionic Hydrogels for Health Monitoring and Human‐Machine Interactions Under Extreme Cold Conditions

Advanced Science, EarlyView.
This study presents an ionic conductive hydrogel (ICH) with excellent conductivity, self‐healing, self‐adhesion, and long‐term stability under extreme cold conditions. It shows significant potential for non‐invasive, continuous health monitoring, conformally adhering to skin without signal crosstalk, enabling real‐time, high‐fidelity signal ...
