CoilForge: Modeled Eddy-Current Antenna Design Service for NDT Probe Makers

A design service that creates custom electrical sensors for identifying different types of metals.

A design service and web tool where an NDT instrument maker or inspection lab specifies a metal-identification task (which alloys to separate, part geometry, standoff) and receives a manufacturable eddy-current antenna specification — coil geometry, frequency, drive parameters — with predicted response separation, replacing months of empirical coil iteration.

Concept

Every eddy-current instrument's discrimination is set by its probe coil — the 'antenna': its geometry, turns, and operating frequency determine field penetration and how cleanly two metals' responses separate. Today, specialty probe development is largely empirical: physical coils are iterated on the bench. CoilForge packages the modeling capability demonstrated in the source paper as a spec-driven service: the customer enters the discrimination problem (e.g., separate two stainless grades on a curved part at a fixed standoff), and gets back a manufacturable coil design plus the predicted signature separation between the target metals. Customers are eddy-current instrument manufacturers adding alloy-identification products, probe houses, and inspection service labs with one-off client parts. Revenue is per-design or by subscription.

Why now

The abstract [0] shows that antenna construction and parameter modeling for the eddy-current identification of metals is now an addressed engineering problem — the probe can be designed by modeling for a stated identification task rather than tuned by trial and error. That converts custom-probe development from months of bench iteration into a spec-driven design pass, which is the precondition for selling probe design itself as a product.

A high-value B2B design service that converts empirical NDT probe development into a predictable engineering workflow, though it relies on a thin evidence base.

Evidence strength
2/5
The provided research snippet is a high-level description of a publication rather than a detailed methodology or result, leaving the actual accuracy and robustness of the modeling unverified.
Market pull
4/5
The named beneficiaries are established industry leaders who currently rely on expensive, time-consuming empirical iteration for custom probe development.
Novelty & moat
3/5
While AlloySnap uses similar modeling for a specific end-product, CoilForge pivots to a design-service model for the manufacturers themselves, filling a gap in the toolchain.
Feasibility
3/5
Building the tool requires deep domain expertise in electromagnetic modeling, but the MVP is a service-based delivery of specs rather than a fully automated software suite.
Wedge clarity
5/5
The wedge is extremely sharp: replacing 'months of empirical coil iteration' with a specific, manufacturable antenna specification for a defined alloy-separation task.
Simplicity / focus
5/5
The idea is focused on a single, clear output (a coil specification) for a single user (probe makers), avoiding platform bloat.

Who benefits

  • ibg NDT Systemscompany

    Builds in-line eddy-current systems for metal testing; a spec-driven antenna design route shortens development of test coils for new alloy-discrimination tasks.

  • FOERSTER Groupcompany

    Long-standing eddy-current testing specialist; modeled antenna parameters would speed delivery of custom probes for customer-specific metal identification jobs.

  • Eddyfi Technologiescompany

    Eddy-current NDT instrument maker; a design service that de-risks probe development supports faster expansion into alloy-sorting applications.

  • Evident (Olympus NDT)company

    Sells portable eddy-current instruments; modeled coil heads would reduce the iteration cost of new probes for metal identification use cases.

  • Mistras Groupcompany

    Inspection services firm that occasionally needs task-specific probes for client parts; buying a modeled design beats internal trial-and-error.
