Many odorants related to manufactured explosives have low volatilities and are barely detectable as odors. We previously reported that zinc metal nanoparticles increased rat olfactory epithelium responses, measured by electroolfactogram (EOG), to several odorants. Here, we report that nanomolar concentrations of zinc metal nanoparticles strongly enhanced olfactory responses to the explosives re...

Biosignals will play an important role in building communication between machines and humans. One of the types of biosignals that is widely used in neuroscience are electrooculography (EOG) signals. An EOG has a linear relationship with eye movement displacement. Experiments were performed to construct a gaze motion tracking method indicated by robot manipulator movements. Three operators looke...

Performing some special tasks using electrooculography (EOG) in daily activities is being developed in various areas. In this paper, simple rotation matrixes were introduced to help the operator move a 2-DoF planar robot manipulator. The EOG sensor, NF 5201, has two output channels (Ch1 and Ch2), as well as one ground channel and one reference channel. The robot movement was the indicator that ...

This paper reports the results of experiments that were conducted with five subjects to determine the reliability of the use of Electro-ocular gram (EOG) for controlling computers. Experiments included vertical and horizontal eye motion. Consideration was given to identify a relationship between the angle of the gaze and signal that could be applied to cover all test subjects and generate the r...

The identification of EOG activity from the electroencephalogram (EEG) recorded from the parietal occipital region is analysed. The occurrence of ocular biosignals from scalp EEGs is mandatory for both the automated and visual analysis of underlying brainwave activity. The most prominent eye-induced artefacts are caused by the potential difference between the cornea and retina, which is quite l...

This paper involves a new method to control and guide mobile robots. In this case, to send different commands is used electrooculography techniques (EOG), so that, control is made by means of the ocular position (eye displacement into its orbit). This control technic can be useful in multiple applications, but in this work is used to guide a autonomous robot (wheelchair) as system to help to pe...

This paper presents a low-noise inverter-based current-mode instrumentation amplifier with tunable gain and bandwidth for electromyogram (EMG) electrooculogram (EOG) biopotential signals, targeting low input noise while maintaining power consumption. The tuning method is based on pseudo-resistors, whereas the due to varactor system that controlled by same control voltage tunes gain. circuit was...

Artifact rejection techniques are used to recover the brain signals underlying artifactual electroencephalographic (EEG) segments. Although over the last few years many different artifact rejection techniques have been proposed (http://dx.doi.org/10.1109/JSEN.2011.2115236[1], http://dx.doi.org/10.1016/j.clinph.2006.09.003[2], http://dx.doi.org/10.3390/e16126553[3]), none has been established as...
