GHS Series Hall Effect sensors
Paragraf’s GHS Series Hall effect sensors deliver the unique properties of graphene into magnetic field sensing applications. Its contamination-free direct-to-wafer deposition technology enables high purity graphene, with a high carrier mobility, to be integrated into sensing technologies. The GHS series of analogue sensors is designed to provide very high-performance measurement, sensing and control for scientific research, battery, healthcare, aerospace, industrial and automotive applications, including:
- Precision magnetic field measurement
- Accurate field gradient mapping and alignment
- High sensitivity current and power measurement
- High precision position, rotation and speed sensing
- Continuous ultra-low power sensing
GHS01AT Graphene Hall Effect Sensor Kit
The GHS01AT Hall effect sensor is optimised for measuring small fields with high resolution (<20 ppm) and therefore suited to provide high performance analogue magnetic field measurements for battery & electric technologies, scientific research, healthcare, aerospace and industrial applications.
The standard GHS01AT Kit includes a GHS01AT sensor and a small interface PCB for ease and convenience of implementation.
- Exceptionally high resolution
- Ultra-low noise performance
- High linearity
- Low power operation & small footprint
- Immunity to in-plane stray fields
Bringing the magnetic field measurement resolution towards that of more complex magnetic sensors, yet with the small size and ease of use of a Hall sensor, the GHS01AT can address magnetic measurement tasks which conventional technologies simply cannot provide an effective solution for.
By utilising a graphene monolayer (just 0.34nm thick) the GHS01AT is not affected by the presence of in-plane stray electromagnetic fields that would severely impact on the accuracy of alternative sensing mechanisms. The small footprint allows good spatial resolution and magnetic measurement in small spaces.
High resolution magnetic field strength measurements and precise position, rotation and speed sensing can all be realised with the GHS01AT.
GHS09CC Engineering Sample Kit
Paragraf’s analogue, single-axis GHS09CC sensor utilises the inherently low noise characteristics of graphene to deliver outstanding field resolution. The two-dimensional nature of graphene results in an inherently negligible planar Hall effect and graphene’s robustness and electron mobility provide unsurpassed temperature and magnetic field operational ranges.
The GHS09CC is available as an engineering sample and supplied as standard with a cryogenic-rated socket for ease of implementation. It delivers to an extraordinary range of application demands. Benefits to be exploited include:
- Operation under extremes of temperature < 1.8 K to 353 K
- Resolution of ppb magnetic field changes over large field ranges > 9 T)
- Operation down to 10 nA, saving power and representing only 5 pW heat dissipation
- Negligible planar Hall effect, aiding precise instrument positioning w.r.t. field direction
GHS Array Starter Kit
The GHS Array Starter Kit has been developed to facilitate battery analysis using arrays of GHS.
- Facilitates simultaneous data collection from up to 8 GHS sensors
- Consists of a main board & probes
- Probes include a temperature sensor for simultaneous temperature measurement and temperature correction of magnetic field measurements
- Interfaces with customers own DAQ and PSU

Graphene electronics device company Paragraf has perfected a proprietary transfer-free process for depositing single-atom thick, two-dimensional materials – including graphene – directly onto silicon, silicon-carbide, sapphire, gallium-nitride, and other semiconductor-compatible substrates. The contamination-free technology is scalable and compatible with existing electronic device manufacturing processes.
Based near Cambridge, UK, Paragraf was launched in 2017 as a spin-out from the Department of Materials Science & Metallurgy at Cambridge University. At its custom R&D and production facility, the company produces the highest-quality large-area graphene, and develops step-change graphene-based electronic devices utilising its expertise in:
- thin film materials production
- solid state structure and device processing
- novel material product application
Harnessing graphene for commercial electronic devices
Paragraf’s contamination and transfer-free production process makes its “next-generation” graphene suitable for commercially viable electronic devices. Paragraf’s graphene is directly compatible with existing electronic device processing and production lines, enabling readily scalable graphene electronic device production.
This production technique enables formation of graphene directly onto semiconductor material surfaces and transparent crystalline substrates. Full coverage with either pristine, functionalised, or multi-layer graphene produces a surface with all the properties required for final product application. This combination of benefits eliminates several processing requirements – increasing productivity while reducing cost.
Paragraf’s first commercial application of graphene in an electronic device is the GHS Series Hall-Effect sensors, which deliver outstanding field resolution without signal conditioning.
The contamination-free direct-to-wafer deposition technology enables high purity graphene, with a high carrier mobility, to be integrated into sensing technologies. The GHS series of analogue sensors is designed to provide very high-performance measurement, sensing and control for scientific research, battery, healthcare, aerospace, industrial and automotive applications.
