Introduction Glaucoma is one of the most common causes blindness and affects more than 70 million people worldwide. The disease characterised by loss retinal ganglion cells associated with a progressive optic neuropathy, resulting in an impairment visual functions, for example, field loss. Nowadays, only modifiable risk factor increase intraocular pressure, its treatment to lower this pressure medication, laser or surgery avoid progression. New methods preventing reversing vision are thus...
Dry electroencephalography (EEG) electrodes provide rapid, gel-free, and easy EEG preparation, but with limited wearing comfort. We propose a novel dry electrode comprising multiple tilted pins in flower-like arrangement. The Flower increases comfort contact area while maintaining ease of use. In study 20 volunteers, we compare the performance 64-channel cap to commercial Multipin sitting supine positions. was rated as significantly improved both channel reliability average impedances...
Abstract Our long-term goal is the development of a wearable warning system that uses electrocutaneous stimulation. To find appropriate stimulation parameters and electrode configurations, we investigate perception amplitude thresholds qualitative perceptions for varying pulse widths, sizes, positions. The upper right arm was stimulated in 81 healthy volunteers with biphasic rectangular current pulses between 20 $$2000\,\upmu \hbox {s}$$ <mml:math...
Abstract Our long-term goal is the development of a wearable warning system that uses electrocutaneous stimulation. Here, we investigated how stimulation pulse amplitude, intervals, and location were perceived in order to select which these three parameters are practical for designing signal. The upper right arm was stimulated 81 healthy volunteers with biphasic rectangular current pulses width 150 µs. Eight electrode pairs placed around arm. Nine varying amplitudes 1 9, equally spaced...
Warning of workers in dangerous situations is crucial. With the aim deriving practical parameters for an electrocutaneous warning stimulation, we explore design dimensions pulse intervals, amplitudes, and locations stimulation a study on healthy volunteers. Using biphasic rectangular current pulses upper right arm 81 participants, they evaluated temporal perception with varying ranging from 200 ms down to 0.5 ms, categorizing it as ’Individual pulses’, ’Pulsating’, ’Vibrating’, or...
Abstract Acoustic or visual warning signals for workers in hazardous situations might fail under loud and/or lowvisibility work situations. A system that uses electrocutaneous stimulation can overcome this problem. The aim of pilot study was to find spatio-temporal patterns appropriate electrical warning. Eight electrode pairs were attached the upper right arm 16 participants. conducted with bi-phasic rectangular pulses 150 μs and an amplitude up 25 mA. Pulse intervals generate a single...
