SEMG-controlled telephone interface for people with disabilities
Journal of Medical Engineering & Technology, 2002This paper proposes the development of a surface electromyographic (SEMG)-controlled telephone interface for the disabled. The system is composed of three major components: (1) a SEMG receiving/signal-processing module; (2) a row-column scanning interface for the telephone dialling pad; and (3) a main controller, the Intel-8951 microprocessor.

A new and fast approach towards sEMG decomposition
Medical & Biological Engineering & Computing, 2013The decomposition of high-density surface EMG (HD-sEMG) interference patterns into the contribution of motor units is still a challenging task. We introduce a new, fast solution to this problem. The method uses a data-driven approach for selecting a set of electrodes to enable discrimination of present motor unit action potentials (MUAPs).

Visualization of activated muscle area based on sEMG
Journal of Intelligent & Fuzzy Systems, 2019Based on HSV gamut space, a visualization system of muscle activity is proposed to study the mapping relationship between hand motion and active areas of upper arm muscle. There is a significant threshold change in the starting and ending points of the active segment in the original EMG signal, and the part that exceeds the threshold TH is the active ...

Prosthetic hand control using speech and sEMG
2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014This paper presents a new prosthetic hand control using speech and sEMG for forearm amputees. sEMG signals can often be affected by operators' biological conditions such as fatigue, sleepiness, flush, etc. Speech signals, in contrast, are relatively unaffected by the operators' biological conditions.

The effect of perspiration on the sEMG amplitude and power spectrum
Journal of Electromyography and Kinesiology, 2012Sweat accumulation underneath surface EMG (sEMG) electrodes is a common problem in workplace studies which compromises electrode adherence to the skin as well as signal fidelity. In this study, the effect of sweat accumulation on signal amplitude and mean frequency (MF) was examined to determine if the sEMG signal becomes altered through the sweat ...

Surface EMG (SEMG): A Synopsis
Biofeedback, 2019Surface electromyography is an electrophysiological modality assessing the electrical activity of skeletal musculature. The Sella protocol is a structured assessment protocol, including static muscle assessment and dynamic muscle assessment, utilizing standardized electrode placements, conditions, and movements during assessment.

A sEMG Classification Framework with Less Training Data
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018Supervised machine learning algorithms, such as Artificial Neural Network (ANN), have been applied to surface electromyograph (sEMG) to classify user's muscular states. This paper introduces a novel framework to design a binary sEMG classifier to distinguish if the user performs a repetitive motion with a dumbbell.

An Adaptive Feature Extractor for Gesture SEMG Recognition
2007This paper proposes an adaptive feature extraction method for pattern recognition of hand gesture action sEMG to enhance the reusability of myoelectric control. The feature extractor is based on wavelet packet transform and Local Discriminant Basis (LDB) algorithms to select several optimized decomposition subspaces of origin SEMG waveforms caused by ...
