Development and testing of a passive Walking Assist Exoskeleton
Publication date: Available online 15 February 2019Source: Biocybernetics and Biomedical EngineeringAuthor(s): Zlatko Lovrenovic, Marc DoumitAbstractThe ability to walk is perhaps the most common indicator of mobility and independence. Regrettably, a large portion of the population is experiencing a loss in mobility due to aging and/or chronic health conditions. There is thus an urgent need to develop systems that would help preserve mobility for individuals in need. One promising solution to this growing problem is Walking Assist Exoskeletons. Current devices mostly rely on powered systems to provide walk assist by applyi...

Publication date: Available online 3 December 2018Source: Biocybernetics and Biomedical EngineeringAuthor(s): Reda Abdelbaset, Yehya H. Ghallab, Yehea IsmailAbstractThe dielectrophoresis (DEP) is the motion of polarizable particles which is a result of the interaction between a non-uniform electric field and the induced dipole moment of these particles. The electro-kinetic DEP is a widely used technique for biological cells’ manipulation, characterization and separation. The electro-kinetic DEP consists of three major configurations, they are; traveling wave dielectrophoresis (twDEP), electro-rotation dielectrophoresis (...

A speech recognition system based on electromyography for the rehabilitation of dysarthric patients: A Thai syllable study
The objective of this study is to develop a speech recognition system for classifying nine Thai syllables, which is used for the rehabilitation of dysarthric patients, based on five channels of surface electromyography (sEMG) signals from the human articulatory muscles. After the sEMG signal from each channel was collected, it was processed by a band-pass filter from 20–450 Hz for noise removal. Then, six features from three feature categories were determined and analyzed, namely, mean absolute value (MAV) and wavelength (WL) from amplitude based features (ABF), zero crossing (ZC) and mean frequency (MNF) from frequ...
