Electrode College Essays Samples For Students

Introduction

In the year 2015, Wang, Doleschel, Wunderlich, and Heinen published a paper in the Journal of Medical Systems [1]. The paper was on a wearable wireless ECG system that was based on the novel 3-Lead electrode placements. After carrying out an experiment for the 3-Lead electrode placements, it was discovered that the distance between the electrodes could further be reduced for efficiency. A smaller sized sensor node being powered by a rechargeable battery would then be developed based on the newly identified electrode positions. A dynamic method of controlling power is also automatically installed in the sensor node for ...

Business Case

It is my hope that this finds you well.
I am writing to report the case of a broken electrode. The broken electrode is a component of a pH meter belonging to the Soil Science Center (“The Agricultural Institute mystery: The case of broken electrode”). The pH meter was borrowed on Monday morning on the date of this email. The Insect Diagnostics Laboratory and the Soil Science Center have for a long time been sharing the equipment. Consequently, the borrowing of the equipment on this particular day was in the ordinary conduct of business in the two laboratories. The ...

Bio fuel cells utilize biocatalysts for the conversion of chemical energy stored in glucose into electrical energy. Bio-catalyzed oxidation of glucose or other organic substances at two electrode interfaces provides a means for conversion of chemical energy into electrical energy. The obtainable power of a fuel cell (P cell) is the product of cell voltage (V cell) and the cell current (I cell)

The ideal voltage id affected by the difference in potential of the oxidizer and fuel as represented in the equation

(E◦1ox - E◦1fuel), with irreversible losses in voltage caused by kinetic limitations of electron movement, (η). Resistance and differences in concentration gradients of the energy source lead to decreased voltage values. As represented below
P cell = ...

Biology

Abstract
This is a practical report on human physiology EMG. The experiment recruited 85 subjects to examine the level of the signal emanating from muscle contraction in the lab. Some of the participants were left-handed while some were right handed. Males and females with varying levels of activity were recruited. The results indicated that more males exhibited maximal compression force than females as attested by the higher numbers that returned quickly to half the clench force. The level of activity of the participants positively correlated to slow return to half of the maximal compression force and reduced signs of ...

Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...

Abstract

This is a practical experiment on ECG with regards to human physiology. The experiment was intended to achieve one primary goal: equip the learner with vital skills pertinent in making rational decisions anchored on scientifically proven facts. The alchemist recruited study participant from both sexes with varying levels of nutritional statuses and physical activities. The foods consumed by each participant were recorded. The results indicated that those who took caffeinated drinks positively correlated to emission of rapid ECG signals demonistrated by the ECG readings.

Long chains of molecules are called polymers. Many small molecular units (called monomers) form polymers, which depending on their arrangement are so useful in everyday life; making materials like silk, wool, or plastic bags. Most of the polymers are organic compounds; it means that they are carbon chains connected to hydrogen, Oxygen or nitrogen atoms. The electrons of these atoms are shared between two atoms that are located in the low energy bonding orbitals. This stops the polymers from making electricity and the electrons play the role of a non-conductor.
In 1997, a set of highly conductive polymers were discovered. ...

Introduction

Wearable Electroencephalography is the resultant evolution of ambulatory Electroencephalogram EEG. Whereby, it is a typical noninvasive technique for taking measurements of brainwaves of a person. The technique is applied in diagnosis related to sleep disorder, epilepsy, and brain computer interfaces. It is made possible by placing the electrodes on the scalp whereby it senses the microvolt signals generated from neuronal activity that is being synchronized in the brain. The ambulatory EEG is bulky whereas the wearable Electroencephalography is small and can be worn on the head.
In this paper we are going to focus on the wearable EEG technology unearthing ...

Abstract
This is a practical experiment on ECG concerning human physiology. The experiment intends to achieve one primary goal: equip the learner with vital skills pertinent in making rational decisions anchored on scientifically proven facts. I chose to study participants from both sexes with varying levels of nutritional statuses and physical activities. We recorded the foods consumed by each participant. The results indicated that those who took caffeinated drinks positively correlated to emission of rapid ECG signals demonistrated by the ECG readings.

Lab Memo: Cyclic Voltammetry: Identification and Quantification of Unknown Concentrations of Substituted Benzoquinones

1.Introduction

Cyclic Voltammetry (CV) measures the redox behavior of electeroactive species and is useful for a whole spectrum of molecules in inorganic chemistry, biochemistry, electrochemisty as well as organic chemistry. A voltammogram is the readout of the energy scan which can be used to determine unknown concentrations. Voltammogram wave shape is very different than in spectrometry and chromatography. The wave is triangular in shape because the y-axis describes the shift in the potential which is the voltage of a working electrode versus a reference electrode. The x axis describes duration in seconds. (Kissinger and Heineman).

Two samples each with an unknown concentration of benzoquinones were analyzed with the instrument, BASi Epsilon-EC.
