Question

In floating electrodes metal electrode make direct contact with the skin.

(a) True

(b) False

The question was posed to me in class test.

Question is taken from Biotelemetry Application on Wimax Networks topic in portion Biomedical Telemetry of Biomedical Instrumentation

Answer 1

Correct option is (b) False

To explain I would say: The electrode consists of a light weighted metalled screen or plate held away from the subject by a flat washer which is connected to the skin. In floating electrode the metal electrode does not make direct contact with the skin. Floating electrodes can be recharged, i.e. the jelly in the electrodes can be replenished if desired.
