Spin-transfer torque magnetic memory as a stochastic memristive synapse for neuromorphic systems.
IEEE transactions on biomedical circuits and systems
Apr 14, 2015
Spin-transfer torque magnetic memory (STT-MRAM) is currently under intense academic and industrial development, since it features non-volatility, high write and read speed and high endurance. In this work, we show that when used in a non-conventional...
A method to accurately estimate the muscular torques of human wearing exoskeletons by torque sensors.
Sensors (Basel, Switzerland)
Apr 9, 2015
In exoskeletal robots, the quantification of the user's muscular effort is important to recognize the user's motion intentions and evaluate motor abilities. In this paper, we attempt to estimate users' muscular efforts accurately using joint torque s...
The influence of push-off timing in a robotic ankle-foot prosthesis on the energetics and mechanics of walking.
Journal of neuroengineering and rehabilitation
Feb 22, 2015
BACKGROUND: Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing. Simple walking models suggest that preempt...
Adaptive Neural Control of a Class of Output-Constrained Nonaffine Systems.
IEEE transactions on cybernetics
Feb 4, 2015
In this paper, we present a novel tracking controller for a class of uncertain nonaffine systems with time-varying asymmetric output constraints. Firstly, the original nonaffine constrained (in the sense of the output signal) control system is transf...
Design of a Robotic System to Measure Propulsion Work of Over-Ground Wheelchair Maneuvers.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Nov 20, 2014
A wheelchair-propelling robot has been developed to measure the efficiency of manual wheelchairs. The use of a robot has certain advantages compared to the use of human operators with respect to repeatability of measurements and the ability to compar...
The influence of the medial meniscus in different conditions on anterior tibial translation in the anterior cruciate deficient knee.
International orthopaedics
Nov 15, 2014
PURPOSE: The purpose of this study was the evaluation of knee laxity in the ACL-deficient knee with combined meniscal tear, meniscal suture and partial medial meniscectomy.
Analysis of operational comfort in manual tasks using human force manipulability measure.
IEEE transactions on haptics
Nov 14, 2014
This paper proposes a scheme for human force manipulability (HFM) based on the use of isometric joint torque properties to simulate the spatial characteristics of human operation forces at an end-point of a limb with feasible magnitudes for a specifi...
A powered prosthetic intervention for bilateral transfemoral amputees.
IEEE transactions on bio-medical engineering
Jul 2, 2014
This paper presents the design and validation of a control system for a pair of powered knee and ankle prostheses to be used as a prosthetic intervention for bilateral transfemoral amputees. The control system leverages communication between the pros...
Biomechanical analysis on neurotypical and autism spectrum disorder people during human-cobot interaction.
Applied ergonomics
Oct 1, 2025
Biomechanical analysis is essential for assessing subjects interacting with robotic setups and platforms. However, in industrial scenarios, workers' biomechanics are assessed mainly through questionnaires and scales which provide limited objectivity....
An elbow passive exoskeleton with controllable assistance: Design and experimental.
The Review of scientific instruments
Feb 1, 2025
A passive exoskeleton is a wearable robotic device that is worn on the exterior of the user's body to provide physical support and facilitate movement. Existing elbow passive exoskeletons have limitations in their assistance capabilities and range of...
