摘要： According to an aspect, there is provided an electric shaver (100, 300a-b, 400, 500a-c) that comprises a first hair-cutting unit (150) that comprises: a first internal cutting member (252); and a first external cutting member (152, 152a, 152b, 152c) arranged to cover the first internal cutting member (252) and wherein the first internal cutting member (252) is movable relative to the first external cutting member (152, 152a, 152b, 152c); wherein the first external cutting member (152, 152a, 152b, 152c) comprises a first skin-contacting area comprising a first plurality of hair-entry openings (266), wherein the first skin-contacting area is arranged, in use, to contact skin. The electric shaver (100, 300a-b, 400, 500a-c) further comprises a second skin-contacting area arranged, in use, to contact the skin and a bi-polar radio frequency (RF) generator unit (120) configured to apply a first polarity RF voltage to the first external cutting member (152, 152a, 152b, 152c), and wherein the entirety of the first external cutting member (152, 152a, 152b, 152c) is configured to conduct the first polarity RF voltage; and wherein the bi-polar RF generator unit (120) is further configured to apply a second polarity RF voltage to the second skin-contacting area.
