This 6 lead ECG cable with graphene coating as noise layer,its Low Triboelectric noise cable (noise value less than 50 uv,about 25-30uv).As graphene coating has much better conductivitity than seme-conductive plastic,to realize the same low triboelectric noise performance,graphene coating only need a thickness of 0.02mm,so as to realized a minimum diameter of the cable.
Separate shielding is another feature
