Wearable electronic device

A wearable electronic device, comprising:

• a first portion (200), wherein the first portion comprises a first conductive area (CA1) on a first inner surface (IS1) of the first portion and a third conductive area (CA3) on a first outer surface (OS1) of the first portion;
• and
• a second portion (300), wherein the second portion comprises one or more second conductive areas (CA2) on a second outer surface (OS2) of the second portion and a fourth conductive area (CA4) on a second inner surface (IS2) of the second portion, wherein the first portion is connected to the second portion,
• wherein a circuit unit (100) is disposed in a second space of the second portion,
• wherein a first node (N1) of the circuit unit is electrically connected to the third conductive area,
• wherein a second node (N2) of the circuit unit is electrically connected to the fourth conductive area,
• wherein the circuit unit is configured to enable an input/output (I/O) unit of the circuit unit in response to the first conductive area and the second conductive areas are triggered.
