Biopotential Electrode Sensors in ECG/EEG/EMG Systems
"... electroencephalography (EEG) systems measure heart, muscle, and brain activity (respectively) over time by measuring electric potentials on the surface of living tissue. Nervous stimuli and muscle contractions can be detected by measuring the ionic current flow in the body. This is accomplished usin ..."

Wearable Biopotential Measurement Using the TI ADS1198 Analog Front-End and Textile Electrodes Signal conditioning and signal quality assessment
"... Abstract — The development of mobile systems for monitoring bioelectric signals outside a hospital environment involves many challenges that do not arise when it is in a controlled environment, like a hospital. The dimensions of these systems are an important factor to consider in order to facilitat ..."

to facilitate their use without interfering with the daily activities of individuals. The purpose of this work is the implementation of a single-supply battery-powered, low power ECG/EMG signal monitoring system based on the ADS1198 Analog Front-End from Texas Instruments. The system was designed to acquire ECG
Continuity and discontinuity of behavioral inhibition and exuberance: Psychophysiological and behavioral influences across the first four years of life.
- Child Development,
, 2001
"... Abstract: Four-month-old infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavior ..."

by measuring the circumference of the child's head in order to select a Lycra stretch cap of appropriate size. The stretch caps have electrodes for EEG recording sewn into the fabric according to the 10-20 system of electrode placement A small amount of abrasive gel (Omni-prep) was inserted into each
Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Spatial attention effects in macaque area V4.
- The Journal of Neuroscience,
, 1997
"... Focal visual attention typically produces enhanced perceptual processing at the psychological level and relatively stronger neural responses at the physiological level. A longstanding mechanistic question is whether these attentional effects pertain specifically to the attended (target) object or t ..."

viewed at a distance of 55 cm. Single-unit activity in area V4 was recorded with 125-m-diameter epoxy-coated tungsten electrodes (A-M Systems) with impedances of 1-5 M⍀. Electrodes were inserted transdurally through a 5-mm-diameter craniotomy by means of a custom guide tube system. Electrode position
AUTOMATED MONITORING OF GROUNDWATER QUALITY WITH ION-SELECTIVE ELECTRODES AND AN APPLICATION AT THE KATO SOULI AREA (NE ATTICA, GREECE).
"... Surface and groundwater resources are important assets for the economic and so-cial welfare of the population of a given area; they are renewable and with proper management, they contribute substantially to sustained development. Unfortunately, the expansion of industrial and agricultural activities ..."

Experimental recordings with the system show spike signals in rat somatosensory cortex as well as alpha EEG activity in a human subject. Index Terms—Analog VLSI, biopotential
Rotating ring-ring electrode theory and experiment
"... The rotating ring-disk electrode (RRDE), first described almost forty years ago by Frumkin and Nekrasov, 1 has proved an invaluable tool for the study of electrochemical reactions. The RRDE consists of two electrodes in a cylindrical holder: a disk of radius r 1 (see Unstable products or intermedi ..."

They applied their technique to the rotating-ring and the rotating-disk electrode and found good agreement with previous studies. In fact, they observed that their analytical approach yielded better accuracy than digital simulation
