Effect of the sEMG electrode (re)placement and feature set size on the hand movement recognition [PDF]

open access: yesNadica Miljkovi\'c, Milica S. Isakovi\'c, Effect of the sEMG electrode (re)placement and feature set size on the hand movement recognition, Biomedical Signal Processing and Control, Volume 64, 2021, 102292, ISSN 1746-8094, 2020
Repositioning of recording electrode array across repeated electromyography measurements may result in a displacement error in hand movement classification systems. In order to examine if the classifier re-training could reach satisfactory results when electrode array is translated along or rotated around subject's forearm for varying number of ...

Mapping the current flow in sacral nerve stimulation using computational modelling

open access: yesHealthcare Technology Letters, 2018
Sacral nerve stimulation (SNS) is an established treatment for faecal incontinence involving the implantation of a quadripolar electrode into a sacral foramen, through which an electrical stimulus is applied.

Drive and measurement electrode patterns for electrode impedance tomography (EIT) imaging of neural activity in peripheral nerve [PDF]

open access: yesHope, J., Vanholsbeeck, F., & McDaid, A. (2018). Drive and measurement electrode patterns for electrode impedance tomography (EIT) imaging of neural activity in peripheral nerve. Biomedical Physics and Engineering Express, 4 (6), 2018
Objective: To establish the performance of several drive and measurement patterns in EIT imaging of neural activity in peripheral nerve, which involves large impedance change in the nerve's anisotropic length axis. Approach: Eight drive and measurement electrode patterns are compared using a finite element (FE) four cylindrical shell model of a ...

Experimental validation of a three-dimensional heat transfer model within the scala tympani with application to magnetic cochlear implant surgery [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2021, 2020
Magnetic guidance of cochlear implants is a promising technique to reduce the risk of physical trauma during surgery. In this approach, a magnet attached to the tip of the implant electrode array is guided within the scala tympani using a magnetic field.

MagNI: A Magnetoelectrically Powered and Controlled Wireless Neurostimulating Implant [PDF]

open access: yesIEEE Transactions on Biomedical Circuits and Systems (TBioCAS), Volume: 14, Issue: 6, Pages: 1241-1252, Dec. 2020, 2021
This paper presents the first wireless and programmable neural stimulator leveraging magnetoelectric (ME) effects for power and data transfer. Thanks to low tissue absorption, low misalignment sensitivity and high power transfer efficiency, the ME effect enables safe delivery of high power levels (a few milliwatts) at low resonant frequencies (~250 kHz)

Scaling of Electrode-Electrolyte Interface Model Parameters In Phosphate Buffered Saline [PDF]

open access: yes, 2014
We report how the impedance presented by a platinum electrode scales with the concentration of phosphate buffered saline (PBS). We find that the constant phase element of the model scales with approximately the log of concentration, whereas the ...

Efficiency of endoneural stimulation with 5- to 24-fold multielectrodes [PDF]

open access: yes, 1998
Optimal selective stimulation of nerve with endoneurally (intrafascicularly) inserted multi-microelectrodes means that each electrode activates, with its own threshold stimulation current, as few distinct motoneurons as possible, preferably only one, If ...
