What feature do the electrodes have to help them grab clothing?

• A. Barbs
• B. Hooks
• C. Magnets
• D. Clips

Answer: (A)

Barbs on the electrode tips provide a secure grip on fabric. Those small projections catch and hold onto clothing fibers, helping the electrode stay in place even as the wearer moves or fabric shifts between the skin and the contact surface. This keeps a stable current path and reduces slipping, which is important for effective conduction through clothing. Other options wouldn’t grip fabric as reliably: magnets rely on metal, hooks can snag or tear fabric without a stable hold, and clips may slip or loosen under movement. Barbs are specifically designed to grab and hold fabric to maintain contact.
