Explanation:
An antistatic wrist strap or ESD wrist strap is a device used to prevent electrostatic discharge
(ESD) by safely grounding a person working on electronic equipment. It consists of a stretchy
band of fabric with fine conductive fibers woven into it. The fibers are usually made of carbon or
carbon-filled rubber, and the strap is bound with a stainless steel clasp or plate. They are usually
used in conjunction with an anti-static mat on the workbench, or a special static-dissipating plastic
laminate on the workbench surface. Computer components are highly sensitive to ESD.
