Claims6
Steering handle for motor vehicles comprising:
- a core;
- a secondary metal about the core;
- a dielectric material between said core and said secondary metal such that a capacitor is defined thereby;
- means for monitoring a capacitance of the capacitor and determining a contact between at least one hand of the driver and the steering handle based on the monitored capacitance;
- and
- a second secondary metal about the core and configured such that the secondary metal and the second secondary metal define a differential capacitor.
