Dry beveling of micropipette electrodes

Journal of Neuroscience Methods, 1980
Beveling or otherwise modifying the tips of micropipettes has been found to improve their performance. Although some success has been reported, especially with wet beveling methods, problems and uncertainties are significant. In this paper we describe both manual and automated dry beveling systems which use a bevel table and bevel plate similar to ...

A micropower dry-electrode ECG preamplifier

IEEE Transactions on Biomedical Engineering, 2000
This paper describes the development of a very low-power preamplifier intended for use in pasteless-electrode recording of the human electrocardiogram. The expected input signal range is 100 microV-10 mV from a lead-II electrode configuration. The amplifier provides a gain of 43 dB in a 3-dB bandwidth of 0.05 Hz-2 kHz with a defined high input ...

Dry electrodes and holder for electro-oculography

Medical & Biological Engineering, 1973
The temporal decrease in electrode-subject resistance was measured for dry silver electrodes placed bitemporally to measure the horizontal component of the electro-oculogram. It was found that the electrode-subject resistance decreased exponentially with time. The average time constant for ten determinations was 3·26 min.

Review of semi-dry electrodes for EEG recording

Journal of Neural Engineering, 2020
Abstract Developing reliable and user-friendly electroencephalography (EEG) electrodes remains a challenge for emerging real-world EEG applications. Classic wet electrodes are the gold standard for recording EEG; however, they are difficult to implement and make users uncomfortable, thus severely restricting their widespread ...

Micropatterned dry electrodes for brain–computer interface

Microelectronic Engineering, 2007
Electroencephalography (EEG) recordings can be used to help paralyzed patients by replacing functionality of damaged neural connections through the aid of a brain-computer interface. Conventional electrodes used for EEG require long skin preparation due to the impedance of the outermost layers of skin.

A Novel Dry Active Electrode for EEG Recording

IEEE Transactions on Biomedical Engineering, 2007
The design and testing of a "dry" active electrode for electroencephalographic recording is described. A comparative study between the EEG signals recorded in human volunteers simultaneously with the classical Ag-AgCl and "dry" active electrodes was carried out and the reported preliminary results are consistent with a better performance of these ...

Non-Invasive Dry Electrodes for EEG

2010
This paper presents a non-invasive dry electrode for electroencephalogram (EEG) acquisition. These electrodes can be integrated in a wearable braincap for wireless EEG that can be used for a long time by patients avoiding the contact gel. This wearable braincap will allow mobility to the patients, while simultaneously having their electrical brain ...

Signal correlation between wet and original dry electrodes in electroencephalogram according to the contact impedance of dry electrodes

2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017
The development of dry electroencephalogram (EEG) electrodes is a topic of interest. A benefit of using dry EEG electrodes is that they do not require any skin preparation. As a result, the condition of the skin with which the dry electrodes come in contact is always different among experiments.

3d Printed Bio-potential Dry Electrodes

2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022
The most commonly used bio-potential electrodes are silver/silver chlorides gel-electrodes (Ag/AgCl electrodes). However, wet electrodes are not suited for daily usage and long-term monitoring. Dry electrodes are the best choice for long-term measurements.

Surface Electromyographic Signals Using Dry Electrodes

IEEE Transactions on Instrumentation and Measurement, 2011
For many electromyography (EMG) applications, a suitable dry electrode would simplify practical implementation of an EMG recording system. Wearable mobility monitoring is an example of such a system. Therefore, surface EMG signals, from Fraunhofer Institute for Biomedical Engineering (IBMT) flexible dry electrodes and Orbital Research electrodes, were ...
