Patent ID: 7152484

Claim:
A sensor element for detecting a physical measurement variable such as a pressure, a temperature, a capacitance, or a gap width between two bodies ( 10 , 20 ) that move in relation to each other during operation and experience high tribological stress, wherein in certain areas between the surfaces of the bodies ( 10 , 20 ) that move in relation to each other, in a surface region of at least one of the bodies ( 10 ), a sensitive layer ( 13 , 30 ) is provided, which is separated from the body ( 10 ) by an insulation layer ( 12 ), characterized in that the insulation layer ( 12 ) is at least essentially comprised of an amorphous, diamond-like carbon, or contains amorphous, diamond-like carbon, oxygen, and silicon, wherein the sensitive layer ( 13 , 30 ) is provided with an abrasion resistant covering layer ( 14 ), which is insulating or has a low electrical conductivity in comparison to the sensitive layer ( 13 , 30 ) and has a thickness of less than 500 nm, wherein a bonding layer ( 33 ) is provided between the insulation layer ( 12 ) and the body ( 10 ) and/or between the sensitive layer ( 13 , 30 ) and the covering layer ( 14 ).
