Radiofrequency Interstitial Tumor Ablation: Dry Electrode

Journal of Endourology, 2003
With the shift in the treatment of small renal tumors from radical extirpative surgery to nephron-sparing approaches, dry-electrode radiofrequency ablation (RFA) has emerged as one potential modality. This application of RF energy leads to the production of heat within the treatment zone secondary to the native impedance of living tissue.

A Motion Interference-Insensitive Flexible Dry Electrode

IEEE Transactions on Biomedical Engineering, 2016
A novel dry electrode is developed to improve the comfortability and the capability of alleviating motion interference by combining microneedles array (MNA) with flexible substrate.Silicon MNA with sharp tips and limited height is fabricated and transferred on a flexible Polydimethylsiloxane (PDMS) substrate through bonding.

Modular multipin electrodes for comfortable dry EEG

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Electrode and cap concepts for continuous and ubiquitous monitoring of brain activity will open up new fields of application and contribute to increased use of electroencephalography (EEG) in clinical routine, neurosciences, brain-computer-interfacing and out-of-the-lab monitoring.

Active cables for use with dry electrodes for electrocardiography

Journal of Electrocardiology, 1978
With the active cables described in this paper, it is possible to record the electrocardiogram with dry electrodes. Simultaneous recordings of the ECG from dry electrodes via the active cables and from conventional electrodes with electrode paste demonstrate that there is no discernible difference in the electrocardiographic waveforms.

Temporal changes in electrode impedance while recording the electrocardiogram with “Dry” electrodes

Annals of Biomedical Engineering, 1973
The temporal change in the approximate impedance of dry silver, stainless-steel and German-silver electrodes applied to the unprepared skin of human subjects was measured using the electrocardiogram as a test signal. In nearly all cases, it was found that “dry” electrodes are really only dry when first applied.

Novel dry electrodes for recording electrodermal activity

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Novel carbon/salt adhesive (CSA) electrodes have been found suitable for collecting electrodermal activity (EDA) signals. Ag/AgCl electrodes are considered the standard for collecting EDA signals, because it highly avoids electrodes' polarization. Ag is an expensive commodity.

A Novel Dry Electrode for Brain-Computer Interface

2009
A brain-computer interface is a device that uses signals recorded from the brain to directly control a computer. In the last few years, P300-based brain-computer interfaces (BCIs) have proven an effective and reliable means of communication for people with severe motor disabilities such as amyotrophic lateral sclerosis (ALS).

A 382nVrms 100GΩ@50Hz Active Electrode for Dry-Electrode EEG Recording

IEEE Transactions on Biomedical Circuits and Systems
This article describes a low noise and ultra-high input impedance active electrode (AE) interface chip for dry-electrode EEG recording. To compensate the input parasitic capacitance and the ESD leakage, power/ground/ESD bootstrapping is proposed. This design integrates chopping stabilization technique to suppress flicker noise of the amplifier which ...
