Claims17
An impact sensor for a vehicle, comprising:
- at least one strain-sensitive sensor element which comprises a sensor material disposed as a layer on a carrier element, said sensor material being a nickel-containing hydrogenated amorphous carbon material, and
- at least two terminals disposed at opposite ends of the carrier element, between which the sensor material is electrically connected.
An impact detection system for a vehicle, comprising at least one impact sensor, said impact sensor comprising:
- at least one strain-sensitive sensor element which comprises a sensor material disposed as a layer on a carrier element, said sensor material being a nickel-containing hydrogenated amorphous carbon material, and
- at least two terminals disposed at opposite ends of the carrier element, between which the sensor material is electrically connected.
A method for impact detection for a vehicle, with at least one impact sensor, said impact sensor comprising:
- at least one strain-sensitive sensor element which comprises a sensor material disposed as a layer on a carrier element, said sensor material being a nickel-containing hydrogenated amorphous carbon material, and
- at least two terminals disposed at opposite ends of the carrier element, between which the sensor material is electrically connected;
- the method comprising the steps of:
- measuring the electrical resistance of the at least one impact sensor;
- and
- identifying an impact situation based on a variation said electrical resistance.
