Using field emission to discharge low voltage static
Many commercially available static eliminators use an array of ionizing needles fed by two current-limited high voltage power supplies of opposite polarity. *
Half of the needles are positive and the other half are negative.

Google "static bar" or "static eliminator".*

This company has been in the business for years. http://products.exair.com/static_eliminators

Edit:  These may or may not be suitable for protecting ESD-sensitive electronic components

Edit 2: *A single needle can also be used, fed with AC.

Carbon yarn is readily available, and its many ~.8 micron fibers generally work well as ion emitters.
