1.	Monopolar needle electrodes are having coatings of which material over the stainless steel wires which are bare only at the tips?(a) carbon(b) calcium(c) sodium(d) teflonThe question was posed to me in examination.My doubt stems from Electrodes for EMG topic in division Bioelectric Signal and Electrodes of Biomedical Instrumentation
Answer» The correct answer is (d) teflon The best EXPLANATION: The MONOPOLAR needle electrode consists of a teflon COATED stainless steel wire. The wire is bare only at the tip. It is found that after the needle has been used a NUMBER of times, the teflon coating will recede, increasing the tip AREA. The needle should be discarded when this happens.
