Energy Stored In A Coaxial Cable

Energy Stored In A Coaxial Cable

A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic field inside...

Generating Electromagnetic Radiations

Generating Electromagnetic Radiations

The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...

Area of Science:

Neuroscience
Biomedical Engineering
Electrophysiology

Background:

Evoked potential experiments demand adaptable and swift adjustments to stimulation and recording parameters.
Existing systems often lack wireless flexibility, hindering real-time experimental control and data acquisition.

Purpose of the Study:

To develop and validate a novel wireless recording system for electrophysiological experiments.
To enable flexible and rapid adjustment of stimulation and recording parameters remotely via an Android application.

Main Methods:

A custom-built, three-unit system (stimulation, recording, control) was designed.
An Android application facilitated wireless communication between a tablet and the control unit up to 5 meters.
The system's performance was evaluated for internal noise, signal fidelity, and precise pulse output timing.

Main Results:

The recording unit demonstrated low internal noise and faithful signal display.
The stimulation unit provided precisely timed pulse outputs upon command.
The system successfully recorded evoked field potentials in the rat dentate gyrus, with responses correlating to stimulation parameters.

Conclusions:

The developed wireless system offers a flexible and efficient solution for electrophysiological recordings.
This technology enhances the ability to control and optimize stimulation and recording parameters in neuroscience research.
The system's performance validates its potential for use in various evoked potential studies.
