Abstract: A device for cutting hair includes a housing, a cutting unit arranged at one end of said housing and having a cutting element. The device includes an electrode, and a voltage source connected to the electrode. The voltage source is configured to provide the electrode with an electrostatic charge so that the electrode is configured to attract charges naturally present in hair cut by the cutting unit without actively charging the cut hair and to consequently draw and/or hold the cut hair away from the cutting element. The hair cutting device also has a sensor, which is arranged to detect a condition relating to the use of the device. The voltage source is activated or deactivated depending on said detected condition.

Abstract: According to an aspect, there is provided a system (10) for treating a part of a body to be treated, comprising a hand-held treating device (20), the treating device (20) comprising a treating unit (30), wherein the treating device (20) is configured such that a treating action of each portion (52) of a plurality of portions (52) of the treating unit (30) can be selectively enabled and disabled independently of the treating action of the other portions (52) of the treating unit (30); and a controller (40) configured to receive information on a predetermined pattern to be created on the part of the body to be treated, and to selectively enable and disable the treating action of the portions (52) of the treating unit (30) according to the received information as the treating device (20) is moved over the part of the body to create the predetermined pattern on the part of the body.
