GRAPHENE MAGNETIC SENSOR

By Phillip Grant Pincock

Bosch Graphene Magnetic Sensor

OBJECTIVES Find how Graphene

can improve sensor performance.

Investigate the material in it’s pressure, magnetic, humidity, gas, and sound pressure devices.

Use bottom up fabrication methods to mass produce the sensors.

The Sensor The magnetic sensor is based

on the Hall effect. Hall Effect – “A magnetic field

induces a Lorentz force on moving electric charge carriers, leading to deflection and a measurable Hall voltage”.

Uses a hexagonal boron nitride substrate.

The Graphene sensor in comparison with a silicon based sensor is significantly better.

Silicon based sensor produced 70 volts per amp-tesla.

Graphene device produced 7000.

Future Plans

Improve applications of Graphene-based sensor to compete with established technologies.

Implement Graphene-based sensors into the market within the next 5-10 years.

Continue looking for ways to use Graphene in commercial technology.
