PCT No. PCT/GB89/00631 Sec. 371 Date Jan. 28, 1991 Sec. 102(e) Date Jan. 28, 1991 PCT Filed Jun. 7, 1989 PCT Pub. No. WO89/11819 PCT Pub. Date Dec. 14, 1989.A low resistance electrical pick-up more particularly for use in a fetal scalp electrode or other bio-sensing electrode, is manufactured by applying to a length of stainless steel wire a first coating layer of nickel, and a subsequent coating layer of silver, an area of the silver layer then being chloridized and coated with bio-compatible plastics material, such as TECOFLEX TM . A layer of copper is preferably provided beween the nickel and silver layers, and it is also preferred for any further length or lengths of non-chloridized silver layer to be coated with a non-conducting varnish to avoid contact with body tissue.
