What’s wrong with silicon?

The production of current silicon sensors is still complex and costly, making them unfit for the future consumer IoT.

Silicon-based sensors

Rigid, brittle and opaque
Batch-processed Clean-room operated
High Cost per sensor Not suitable for single-use
Large carbon footprint for silicon refinement & foundry

Graphene is the next-generation material for sensing.

Awarded the Nobel Prize in 2010, graphene has given rise to a new field of science (2D nanoelectronics) which is already opening up astonishing new possibilities for a frugal and revolutionary technology. As a two-dimensional, i.e. a volume-less material, electrical currents are forced to flow across graphene surface, optimizing their coupling with the environment, leading to high-precision, versatile sensors that can accurately target trace levels of multiple analytes such as contaminants or pathogens simultaneously.

GRAPHEAL SECURES €2.5M FROM EIC ACCELERATOR PROGRAM TO DEVELOP FAST, FIELD-DEPLOYABLE GRAPHENE SENSORS FOR ULTRA-TRACE, REAL-TIME PFAS DETECTION

PFAS, known as “forever chemicals,” are increasingly detected across the world and are to date impossible to detect in the field. Our device PFAST is the deep tech answer to this problem. This June marks for Grapheal , the kick-off month of the EIC Accelerator Grant from the European Innovation Council supporting PFAST. By enabling easy testing at point of need, our sensing platform could allow for more frequent PFAS monitoring as required by new 2026 EU Drinking Water Directive. See more
