Novel dry electrodes for ECG monitoring
Physiological Measurement, 2007The development, fabrication and characterization of two novel dry bioelectrodes--conductive and capacitive ones--for biopotential monitoring are presented. The new electrodes have the potential to improve the applicability of dry electrodes in ambulant recording of ECG by reducing motion artifacts as well as the contact impedance to the skin ...

Dry electrode for the measurement of biopotential signals
Science China Information Sciences, 2011This paper introduces a kind of silicon-based dry electrode for measuring biological signals. It uses microneedle arrays to penetrate into the stratum corneum to reduce skin impedance. The dry electrode requires neither skin preparation nor the electrolytic gel, is easy to use and causes no skin allergy.

Dry beveling of micropipette electrodes
Journal of Neuroscience Methods, 1980Beveling 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, 2000This 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, 1973The 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, 2020Abstract 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, 2007Electroencephalography (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, 2007The 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
2010This 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 ...

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.
