Data-Driven Real-Time Magnetic Tracking Applied to Myokinetic Interfaces.
IEEE transactions on biomedical circuits and systems
May 19, 2022
A new concept of human-machine interface to control hand prostheses based on displacements of multiple magnets implanted in the limb residual muscles, the myokinetic control interface, has been recently proposed. In previous works, magnets localizati...
[Low-field magnetic resonance imaging : Just less expensive or completely different?].
Der Radiologe
Mar 8, 2022
Over the years the development of field strength in magnetic resonance imaging (MRI) has continued to increase from the low-field systems in the early years (0.2-0.5 T) to 1.5 T to 3 T to 7 T and more. In the last 2 years, there has been a renewed in...
Mixed Fault Classification of Sensorless PMSM Drive in Dynamic Operations Based on External Stray Flux Sensors.
Sensors (Basel, Switzerland)
Feb 5, 2022
This paper aims to classify local demagnetisation and inter-turn short-circuit (ITSC) on position sensorless permanent magnet synchronous motors (PMSM) in transient states based on external stray flux and learning classifier. Within the framework, fo...
Fault Diagnosis of Permanent Magnet DC Motors Based on Multi-Segment Feature Extraction.
Sensors (Basel, Switzerland)
Nov 11, 2021
For permanent magnet DC motors (PMDCMs), the amplitude of the current signals gradually decreases after the motor starts. Only using the signal features of current in a single segment is not conducive to fault diagnosis for PMDCMs. In this work, mult...
Ferromagnetic soft catheter robots for minimally invasive bioprinting.
Nature communications
Aug 20, 2021
In vivo bioprinting has recently emerged as a direct fabrication technique to create artificial tissues and medical devices on target sites within the body, enabling advanced clinical strategies. However, existing in vivo bioprinting methods are ofte...
A Machine Learning Enabled Wireless Intracranial Brain Deformation Sensing System.
IEEE transactions on bio-medical engineering
Nov 19, 2020
A leading cause of traumatic brain injury (TBI) is intracranial brain deformation due to mechanical impact. This deformation is viscoelastic and differs from a traditional rigid transformation. In this paper, we describe a machine learning enabled wi...
MagWorm: A Biomimetic Magnet Embedded Worm-Like Soft Robot.
Soft robotics
Aug 19, 2020
Emerging worm-like soft robots with various soft materials and different actuation mechanism have been frequently discussed. It is very challenging for soft robots in realizing a fast and untethered crawling. In this article, a biomimetic magnet embe...
Automated detection of the head-twitch response using wavelet scalograms and a deep convolutional neural network.
Scientific reports
May 20, 2020
Hallucinogens induce the head-twitch response (HTR), a rapid reciprocal head movement, in mice. Although head twitches are usually identified by direct observation, they can also be assessed using a head-mounted magnet and a magnetometer. Procedures ...
3D Fabrication of Fully Iron Magnetic Microrobots.
Small (Weinheim an der Bergstrasse, Germany)
Mar 4, 2019
Biocompatibility and high responsiveness to magnetic fields are fundamental requisites to translate magnetic small-scale robots into clinical applications. The magnetic element iron exhibits the highest saturation magnetization and magnetic susceptib...
Magnetic γ-cyclodextrin polymer with compatible cavity promote the magnetic solid-phase extraction of microcystins in water samples.
Analytica chimica acta
Dec 21, 2018
Microcystins (MCs), which are produced by eruptive cyanobacteria, seriously threaten the health of humans for their poisonousness. Herein, a facile strategy was introduced to synthesize the magnetic γ-cyclodextrin polymer (FeO@PDA@γ-CDP) composite an...
