Using a Cocontraction Ratio to Predict Antagonistic Behavior During Elbow Motion [PDF]
arXiv, 2012 Inverse dynamics methods for muscle forces prediction are globally unable to predict antagonistic activity during a joint motion. This is due to a lack of physiological information describing how forces are shared between flexors and extensors. The aim of this study is the definition and the use of a new EMG-based cocontraction ratio in an inverse ...

Interactive versus non-interactive locally differentially private estimation: Two elbows for the quadratic functional [PDF]
arXiv, 2020 Local differential privacy has recently received increasing attention from the statistics community as a valuable tool to protect the privacy of individual data owners without the need of a trusted third party. Similar to the classical notion of randomized response, the idea is that data owners randomize their true information locally and only release ...

Advanced Science, EarlyView.A highly stretchable strain sensor is presented, that leverages controlled crack formation and ion bridging in a polyvinyl chloride gel/graphene to achieve exceptional sensitivity (gauge factor up to 1.5 × 10⁶) and mechanical stability. By optimizing plasticizer properties, the conductive pathways are finely tuned, enabling robust, real‐time monitoring

A light-weight, multi-axis compliant tensegrity joint [PDF]
arXiv, 2015 In this paper, we present a light-weight, multi- axis compliant tenegrity joint that is biologically inspired by the human elbow. This tensegrity elbow actuates by shortening and lengthening cable in a method inspired by muscular actuation in a person.

Design, Characterization, and Validation of a Variable Stiffness Prosthetic Elbow [PDF]
Transaction on Robotics, Volume 41, 2024Intuitively, prostheses with user-controllable stiffness could mimic the intrinsic behavior of the human musculoskeletal system, promoting safe and natural interactions and task adaptability in real-world scenarios. However, prosthetic design often disregards compliance because of the additional complexity, weight, and needed control channels.
