Sentences with phrase «electrode surfaces during»

Dendrites - deposits that form on electrode surfaces during the charging process - cause the batteries to short circuit, leading to serious safety hazards.

Why It Matters: The device provides a way to understand the basic breakdown reactions, material build - up, and other processes at the electrode surface during operation.

Not exact matches

The device is an improved version of a clinical tool called an electrode grid, which is a plastic or silicone - based grid of electrodes that is placed directly on the surface of the brain during surgery to monitor the activity of large groups of neurons.

These electrodes must have a high surface area per unit weight, high electrical conductivity and capacitance and be physically robust so they do not degrade during operation in liquid or hostile environments.

«With our design, zinc ions are reduced and deposited on the exposed back surface of the zinc electrode during charging,» said Higashi, lead author of the study.

«Epidural stimulation electrodes are implanted during surgery and are located right on the surface of the spinal cord, so they require little current to activate the spinal cord,» Moritz explained.

When using surface electrodes, the equipment detects the voltage in any number of muscle fibers that are close to the surface of the skin, which may or may not be innervated quasi-randomly at any given moment during a muscle action (Reaz et al. 2006).

The presence of different levels of muscle activity has been observed both using surface electrodes and fine wire (intramuscular electrodes) and during maximal voluntary isometric contraction (MVIC), resistance training exercises, and normal humans movements such as gait.
