We provide an open access dataset of High densitY Surface Electromyogram (HD-sEMG) Recordings (named “Hyser”), a toolbox for neural interface research, and benchmark results pattern recognition EMG-force applications. Data from 20 subjects were acquired twice per subject on different days following the same experimental paradigm. 256-channel HD-sEMG forearm muscles during dexterous finger manip...

Salenius, Stephan, Karin Portin, Matti Kajola, Riitta Salmelin, synaptic currents flowing mainly in the fissural cortex. It and Riitta Hari. Cortical control of human motoneuron firing allows noninvasive monitoring of cortical activity with a during isometric contraction. J. Neurophysiol. 77: 3401–3405, reasonable spatial accuracy while maintaining an excellent 1997. We recorded whole scalp mag...

The common use of mobile terminals is for text input. However, mobile terminals cannot be equipped with sufficient amount of keys because of the physical restrictions. To solve this problem we developed an input method using surface electromyogram (sEMG), treating arm muscle movements as input signals. This method involves no physical keys and can be used to input Japanese texts. In our experim...

The purpose of this study is to investigate behaviors of motor units of m. biceps brachii (biceps short head muscle) during flexion movements in wide range of elbow joint angle. In this study, eight surface electromyograms(EMGs) were measured during flexion movements at constant angular velocity (isovelocity) and against constant torque in wide range (from 0 [deg] to 120 [deg]) of elbow joint a...

With collaborative robots and the recent developments in manufacturing technologies, physical interactions between humans represent a vital role performing tasks. Most previous studies have focused on robot motion planning control during execution of task. However, further research is required for direct contact human-robot or robot-robot interactions, such as co-manipulation. In co-manipulatio...

Electrogastrography (EGG) appears to be useful method to evaluate the gastric motility as noninvasive approach. However, it is not known what EGG means. The aim of this study is to make clear the meanings of electrical activity recorded dy EGG for gastric motility. EGG recorded by cutaneous electrodes was compared to gastric electromyogram recorded by serosal electrodes and gastric mechanical a...
