Graphene is a revolutionary material that is changing the way we make electronic devices. Paragraf is the world’s first company to use graphene to mass produce electronic devices using standard semiconductor processes. Our high-performance graphene sensor technology brings magnetic field measurement resolution towards that of more complex magnetic sensors, yet with the ease of use of a Hall sensor.
Graphene Hall sensors are ideal for automotive applications such as positional, rotational, and current sensing. They offer instantaneous response, wide measurement range, low power consumption, and ease of use. Post-test calibration and stress sensing are not required for automotive applications, which simplifies the peripheral electronics and reduces the need for amplification or eliminates it completely. Additionally, spinning current and demodulation circuitry is easier to implement with graphene sensors.
