Capacitive sensor device, steering wheel comprising capacitive sensor device, method of operating capacitive sensor device and/or steering wheel, and vehicle comprising capacitive sensor device

The invention relates to a capacitive sensor device (10) for detecting the presence of a human body part in a detection region of the sensor device (10), to a steering wheel (100) comprising a capacitive sensor device (10), to a method for operating a capacitive sensor device (10) or a steering wheel (100), and to a vehicle comprising a capacitive sensor device (10). The sensor device (10) comprises a first sensor electrode (11) having a first electrode portion (21), a second sensor electrode (13) having a second electrode portion (22), and a second electrode portion (22) for determining a measurement variable (UMess, IMess; b < 1 > to B < 2 >; b2-B1) of at least one first sensor electrode (11), the measured variable being based on a current difference (I1-I2; B1-B1) between a first current (I1) flowing in a first electrode portion (21) of the at least one first sensor electrode (11) and a second current (I2) flowing in a second electrode portion (22) of the second sensor electrode (13); i2-I1), the measuring
