Does EMG control lead to distinct motor adaptation?

Frontiers in Neuroscience, 2014
Powered prostheses are controlled using electromyographic (EMG) signals, which may introduce high levels of uncertainty even for simple tasks. According to Bayesian theories, higher uncertainty should influence how the brain adapts motor commands in ...

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

Advanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Visual attention, EEG alpha power and T7-Fz connectivity are implicated in prosthetic hand control and can be optimized through gaze training

Journal of NeuroEngineering and Rehabilitation, 2019
Background Prosthetic hands impose a high cognitive burden on the user that often results in fatigue, frustration and prosthesis rejection. However, efforts to directly measure this burden are sparse and little is known about the mechanisms behind it ...

Newcastle visual cortical prosthesis

, 2019
Optogenetics is a gene therapy technique which holds lots of potential as a neural interface but also has lots of challenges. It is currently under trial both in the US and Europe for use in a retinal prosthesis form of visual restoration for those with Retinitis Pigmentosa. These trials have been underway[for full text, please go to the a.m. URL]

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

The effect of weight-bearing training with visual feedback on balance and prosthetic loading in trans-tibial amputees following vascular disease – a pilot randomized control trial

Annals of Medicine
Purpose Asymmetrical weight-bearing on trans-tibial prosthesis at the initial prosthetic fitting results in a modified gait and secondary disorders. The pilot study will examine the feasibility of the weight-bearing training with visual feedback in trans-

Mapping of Physiological Signals From Wireless Battery‐Free Implants With Plane‐Wave Ultrasound Imaging

Advanced Materials Technologies, EarlyView.
Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.
