Electrodes: Overview

2.2K
 Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...

Potentiometry: Types of Electrodes

1.3K
Reference electrodes serve as a stable reference point for potentiometric measurements, while indicator and working electrodes react to variations in the composition of a solution.
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...

Area of Science:

  • Otorhinolaryngology
  • Biomedical Engineering
  • Neurosurgery

Background:

  • Cochlear implant (CI) technology relies on precise electrode array placement for optimal auditory restoration.
  • Anatomical variations in the cochlea, even in normal cases, necessitate adaptable electrode designs.

Observation:

  • MED-EL's FLEX electrode array is available in five lengths to accommodate size variations in normal cochlear anatomy.
  • Significant anatomical diversity exists within malformed inner ears, requiring specialized solutions.

Findings:

  • MED-EL collaborates with surgeons globally to develop custom-designed electrode arrays for patients with unique cochlear needs.
  • Translational research has led to the successful implantation of diverse electrode array designs in patients requiring special cochlear solutions.

Implications:

  • Tailored electrode array designs enhance the efficacy of cochlear implantation across a spectrum of cochlear anatomies.
  • Personalized approaches in CI surgery improve patient outcomes and technological benefits.
