Precise magnetic fields through embroidered induction structures:

Where conventional winding coils reach their mechanical limits, textile magnetic field coils open up new freedoms in design, ergonomics and integration.

Magnetic field systems are used in many applications in medicine and veterinary medicine, such as in therapy and rehabilitation applications, in mobile systems, or in anatomically close applicators. At the same time, the requirements are changing: devices should become lighter, conform better to the body, and be integrable into textile carriers.

Our embroidered conductor structures resolve the conflict between electrical engineering and mechanical engineering: reproducible electrical parameters at high flexibility and robustness.

As OEM suppliers We develop and manufacture textiles induction coils for Magnetic field applicators from Prototyp to Serial Production.

Why textile magnetic field coils are crucial for OEM systems

Traditional wound coils are often bound to a rigid coil former. This makes flat designs, anatomical contours, and long bending cycles difficult. Textile magnetic field coils, on the other hand, are Near-net-shape on flexible surfaces They are manufactured and can be incorporated into bandages, mats, blankets or integrated applicator components.

A textile magnetic field coil is an induction structure in which the conductor is connected by CNC embroidery on a textile backing precisely positioned and fixed instead of lying as a wire winding on a rigid coil body.

The key difference to a classic winding coil is the Low-stress ladder storage on a flexible surface, whereby geometric freedom and Flexural fatigue strength climb.

If you are looking for an introduction to applications and functionality, you will find an overview here: Textile coil mats for medicine and therapy.

You will particularly benefit from:

anatomically close applicators with a constant distance to the tissue

ultra-flat designs without bulky coil bodies

mobile systems with strict weight and comfort requirements

segmented applications with definable field zones

Are you planning a flexible applicator geometry or do you want to reduce weight and structure?

Technological advantage through embroidered ladder guides

CNC-assisted technical embroidery instead of mechanical winding tension

The basis is our CNC-assisted technical embroideryUnlike traditional winding methods, we lay conductors low-tension application on textile substratesThe ladder is securely fixed without unnecessary mechanical stress.

Precision and reproducibility via CAD/CAM

Each coil design is developed in the CAD system and transferred directly to CNC manufacturing. This results in a high degree of design freedom combined with high repeatability.

Precise ladder positioning enables:

constant inductance values across the series
Targeted field distribution through defined winding spacing
Zoning, i.e., different field strengths in a textile surface

Mechanical resilience for movable applicators

When bent, the textile absorbs tensile and compressive forces. The conductor remains largely unloaded. This increases flexural strength and lifespan, even with intensive use and repeated movement.

Technical parameters that we design for your system

To ensure your textile magnetic field coil fits into the electronics, geometry and series production process, we define the key parameters together with your development team:

Inductance: Target-dependent according to geometry and number of turns
Resistance and thermal load: Material, conductor cross-section, duty cycle
Number of turns, turn spacing and conductor routing: Field pattern, homogeneity, zoning
Segmentation / Zoning: multiple field zones in a textile surface
Connection concept: Cable set, contact pad, plug or push button interface
Protection concept: Insulation, partial or full-surface lamination

If you would like to combine other functions in addition to the coil, It's also worth taking a look at our Smart textile approaches in the e-textiles sector.

If you already have target values or measurement data, we can quickly compare design variants to your requirements.

Advantages over conventional magnetic field systems

Compared to copper coils on rigid bodies or printed circuit board designs, textile structures offer clear advantages for device manufacturers:

Ultra-thin design for discreet integration into wearables, bandages and mats
Breathability and comfort, since the air permeability of the carrier material is maintained
weight loss, because heavy coil bodies and potting compounds can be eliminated
geometric freedom, including cutouts, anatomical curves and near-end contours
Series consistency, since conductor paths and distances are reliably reproducible within the process

Material expertise and structure

The performance of a textile magnetic field coil depends heavily on the material combination. We tailor the conductor and support to your target parameters.

Conductor materials

Highly flexible copper strands made from the finest individual wires for maximum flexibility
Insulated enamelled wires for high numbers of turns in a small space
special alloys in cases requiring corrosion resistance or specific resistances

Carrier textiles

Nonwovens and woven fabrics for high dimensional stability and precise field profiles
Elastic knits for applicators with stretching, for example knee braces
Spacer fabric (3D textiles) for the combination of magnetic field function and padding

Typical designs range from highly flexible designs for wearables to dimensionally stable setups when maximum reproducibility of the field image is paramount.

Application areas range from human medicine to veterinary technology

Medical therapy and rehabilitation

Textile magnetic field coils are suitable for ergonomic, body-worn applicators. Instead of bulky stand-alone devices, wearables are created that can adapt to the spine, knee, or neck while simultaneously enabling a defined geometry and field distribution.

Veterinary medicine and large animal therapy

Mechanical robustness is crucial in animal blankets and mats. Embroidered spools withstand dynamic stresses caused by movement, rubbing, or rolling. Suitable surface finishes and lamination can facilitate cleaning.

Inductive functions and combination systems

Beyond therapy applicators, we manufacture structures for:

inductive energy transfer for sealed or encapsulated medical devices
Combination systems, for example, magnetic field coils plus textile heating elements on a carrier surface

Integration and connection technology

The transition from flexible coil to electronics often determines suitability for series production. We offer solutions that can be integrated into your manufacturing processes:

Pre-assembled cable sets with direct contact on the textile
Interface design with push buttons, connectors or contact pads according to specification
Insulation and protection through partial or full-surface lamination, tailored to the media and cleaning process.

Do you already have an electronics platform and are looking for a secure textile connection?

Coordinate integration solution

Your partner for B2B development and series production

We support system manufacturers from feasibility studies to series production. Close coordination with your development team is crucial to ensure that inductance, resistance, and field strength are translated into a textile design that can be manufactured reliably.

Our process

Specifications: Define geometric and electrical requirements
Prototyping: Rapid sampling for validating the field curves
Validation: Evaluate contacting and laminating options
Series: Scalable manufacturing with documented quality control

Quality and serial production capability

For OEM projects, reproducible parameters and stable processes are crucial. That's why we rely on manufacturing designed for series production:

defined CAD/CAM database for repeatable conductor routing
Electrical testing according to agreed criteria (e.g. resistance/conductivity per design)
Reliable contacting processes and documentable protection concepts
Scaling from prototype through pre-production to series production with quality control

This way you get a textile magnetic field coil that can not only be developed, but also reliably fits into your product and your supply chain.
