Quantum Computing & Cryogenics

Silicon sensors dissipate milliwatts of heat, wasting the ~14 µW cooling budget of a dilution refrigerator. Paragraf Graphene Hall Effect Sensors dissipates power in a low range with limited carrier freeze-out. Map up to 30T fields with zero Planar Hall Effect.

Aerospace & Extreme Environments

Every gram of shielding is a gram of payload lost. Paragraf Graphene Hall Effect Sensors are naturally impervious to displacement damage and NPL-validated to survive 30,000x the typical ISS neutron radiation dose rate. Miniaturise your CubeSat ADCS with unshielded, solid-state magnetometry.

Nuclear Fusion

Inductive Mirnov coils rely on integration; over long plasma pulses (>1000s), low-frequency noise compounds. Paragraf Graphene Hall Effect Sensors enable direct, steady-state DC measurement with low integrator drift, mapping the last closed flux surface.
