A High‐Precision Dynamic Movement Recognition Algorithm Using Multimodal Biological Signals for Human–Machine Interaction

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
This article describes a multimodal fusion data acquisition and processing system about electromyography for dynamic movement recognition and bioelectrical impedance for key posture recognition. In addition, a new dynamic–static fusion algorithm strategy is designed.

Simultaneous sEMG Recognition of Gestures and Force Levels for Interaction With Prosthetic Hand

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
The natural interaction between the prosthetic hand and the upper limb amputation patient is important and directly affects the rehabilitation effect and operation ability. Most previous studies only focused on the interaction of gestures but ignored the

Soft Magnetic Sensor Array for Amphibious Measurement of 3D Muscle Deformation Distribution for Human Motion Recognition

Advanced Intelligent Systems, EarlyView.
This article develops a soft magnetic sensor array to extract 3D and distributional muscle deformations, which has highly consistent measurements in amphibious environments, robustness to hydraulic pressure, and about 200 ms faster response than an inertial measurement unit, achieving over 98% classification accuracy and below 3% phase estimation ...

A Psychometric Platform to Collect Somatosensory Sensations for Neuroprosthetic Use

Frontiers in Medical Technology, 2021
Somatosensory neuroprostheses exploit invasive and non-invasive feedback technologies to restore sensorimotor functions lost to disease or trauma. These devices use electrical stimulation to communicate sensory information to the brain.

Toward personalizing prosthesis prescription: A take‐home study of three microprocessor‐controlled prosthetic knees: A randomized crossover study

PM&R, EarlyView.
Abstract Background Previous studies on microprocessor‐controlled prosthetic knees (MPKs) often investigate benefits of MPKs as a class of knees rather than clinically relevant differences between specific knees, despite their distinct features. Objectives To systematically evaluate and report outcomes associated with three commercially available MPKs ...

POSTURAL SWAY IN LOWER EXTREMITY AMPUTEES AND OLDER ADULTS MAY SUGGEST INCREASED FALL RISK IN AMPUTEES

Canadian Prosthetics & Orthotics Journal, 2020
BACKGROUND: Falls can be detrimental to overall health and quality of life for lower extremity amputees. Most previous studies of postural steadiness focus on quantification of time series variables extracted from postural sway signals. While it has been

Sprint Start Kinetics of Amputee and Non-Amputee Sprinters

PLOS ONE, 2016
The purpose of this study was to explore the relationship between the forces applied to the starting blocks and the start performances (SPs) of amputee sprinters (ASs) and non-amputee sprinters (NASs). SPs of 154 male and female NASs (100-m personal records [PRs], 9.58-14.00 s) and 7 male ASs (3 unilateral above knee, 3 unilateral below knee, 1 ...

Kinematics and directionality of body turning in water striders (Gerris argentatus) on the water surface

Insect Science, EarlyView.
This graphical abstract illustrates the kinematics and directionality of body turning in water striders (Gerris argentatus). The top image shows a water strider making turns, with arrows indicating possible directions and a dashed line tracing its path, highlighting its dynamic turning capabilities.

Digitizing Dignity: Analyzing Digital Twins Through the Lens of Multidimensional Human Dignity

Bioethics, EarlyView.
ABSTRACT In precision medicine, digital twins—virtual models of patients created using personalized data and advanced machine learning—are potentially changing healthcare by predicting health outcomes and guiding medical decisions. However, their use raises complex ethical questions, particularly concerning their relationship to human dignity. Patients
