A fetal electrocardiographic electrode.

A FETAL ELECTROCARDIOGRAPHIC ELECTRODEt Although it is sixty years since the first fetal electrocardiogram (FECG) was recorded by Cremer,1 it is only in recent years that attempts have been made to improve the FECG signal-to-noise ratio so that FECG configuration changes can be evaluated and the FECG used as a reliable trigger for automatic fetal heart rate (FHR) counting circuits. While the FE...

Multi-electrode arrays technology for the non-invasive recording of neural signals: a review article

The recording of electrophysiological activities of brain neurons in the last half-century has been considered as one of the effective tools for the development of neuroscience. One of the techniques for recording the activity of nerve cells is the multi-electrode arrays (MEAs). Microelectrode arrays (MEAs) are usually employed to record electrical signals from electrogenic cells like neurons o...

Flexible carbon nanotubes electrode for neural recording.

This paper demonstrates a novel flexible carbon nanotubes (CNTs) electrode array for neural recording. In this device, the CNTs electrode arrays are partially embedded into the flexible Parylene-C film using a batch microfabrication process. Through this fabrication process, the CNTs can be exposed to increase the total sensing area of an electrode. Thus, the flexible CNTs electrode of low impe...
