ACES Technology: The World's First Commercial-Scale AC Electrospinning Platform
TruSpin's ACES Technology is the world's first commercial-scale platform for alternating current (AC) electrospinning — the manufacturing process behind everything TruSpin makes. Conventional electrospinning is a direct current (DC) process, limited to one spinning jet at a time. ACES replaces that single, static high-voltage field with an alternating current field, protected under U.S. Patents US20220145495A1 and US20220251732A1, so TruSpin can produce nanofibers at industrial volume without the defects and material limits that cap out DC methods.
Whether you're evaluating ACES for a research collaboration or a production-volume supply contract, this is the technical grounding you need: what ACES is, how the process works, how it stacks up against DC electrospinning, and why it's the foundation of every nanofiber product TruSpin builds — from PFAS-destroying water filters to tissue-engineering scaffolds.

What Is AC Electrospinning (ACES)?
Electrospinning is a manufacturing process that uses an electric field to draw a liquid precursor into continuous fibers thinner than a human hair — often measured in nanometers. TruSpin's proprietary version of this process, ACES (Alternating Current Electrospinning), replaces the single, fixed high-voltage field used in conventional electrospinning technology with an alternating one. That one change is the difference between a lab technique and an industrial manufacturing process.
Where conventional electrospinning relies on one charged spinning electrode producing a single jet, ACES is engineered to sustain many spinning jets simultaneously across production-scale equipment — without the bead defects (thickened, clumped sections that interrupt an otherwise uniform fiber) that limit how far high-output DC systems can scale.

How ACES (Alternating Current Electrospinning) Technology Works
At a high level, ACES follows five steps:
- A liquid precursor — a polymer, ceramic, or other material dissolved or suspended in a carrier solvent — is fed to a spinning electrode.
- A high-voltage alternating current is applied across wire electrodes, generating an electric field that oscillates instead of staying fixed.
- The oscillating field pulls the precursor into a continuous, whipping spinning jet, stretching it into a nanofiber as the solvent evaporates.
- Because the field alternates, the spinning electrode can sustain many jets at once across the production line — not the single jet a DC electrospinning process is limited to.
- Fibers are collected via roll-to-roll deposition directly onto a substrate or medium, producing nanofibrous structures ready for downstream processing — or, for TruSpin's own product lines, directly into finished formats like membranes, mats, or yarn.
The headline number: TruSpin's base ACES configuration delivers 20,000 times the production output of a single DC electrospinning spinneret — using the exact same process for a research sample as for a commercial-volume contract. No switching methods after piloting.
AC vs. DC Electrospinning: Why the Difference Matters
Every limitation that keeps electrospinning a lab-scale technique traces back to one design choice: a fixed, direct-current field. Switching to an alternating field changes what's physically possible at production scale:
| Factor | DC Electrospinning | TruSpin ACES |
|---|---|---|
| Output | Single jet, low throughput | Many simultaneous jets — 20,000x a single DC spinneret |
| Fiber Defects | Prone to beading at high output | Non-charged collection surfaces reduce bead defects |
| Additive Tolerance | Limited — particles disrupt the charged jet | High tolerance for additives/particles in the precursor |
| Material Range | Narrower — struggles outside optimized polymers | 20+ polymer, organic, and inorganic material families |
| Scale-Up Path | Often requires switching methods after piloting | Same process, research sample through commercial contract |
| Operating Environment | Sensitive to temperature and humidity swings | Wide temperature/humidity range suited to industrial settings |
This is the short version. For the full technical breakdown — fiber alignment, jet whipping instability, frequency effects, and cost — see AC vs DC Electrospinning.
TruSpin's ACES Advantages
- Patent-protected process. US20220145495A1 and US20220251732A1 cover TruSpin's AC electrospinning method.
- One process, every scale. From small-batch research runs to full commercial-volume manufacturing, TruSpin never switches methods after proving a concept out.
- Broadest material range in the category. 20+ polymer, organic, and inorganic material families — including exotic compositions other production methods can't achieve.
- Engineered by nanomaterials specialists. Led by CEO Dr. Anthony Brayer and a dedicated biomedical R&D engineering team.
- Safer by design. ACES uses solvent chemistries with minimal safety hazards compared to conventional synthetic fiber production.
What ACES Nanofibers Are Used For
Because ACES gives precise control over fiber diameter, alignment, porosity, and cross-linking — and tolerates additives DC methods can't — the same core process supplies a wide range of industries:
| Industry | Application |
|---|---|
| Water Treatment | Polyceramic nanofiber membranes that filter, detain, and destroy PFAS in municipal water systems — see the PFAS Case Study. |
| Filtration | High-surface-area filtration media for industrial and consumer applications. |
| Advanced Textiles | Nanofibrous twine, yarn, and flexible thermal protection materials. |
| Life Sciences | Cell culture scaffolding and tissue-engineering substrates for biomedical researchers. |
| Alternative Protein | Scaffolding for cultivated meat — demonstrated through collaborations with Fractal Foods and Van Heron Labs. |
| Energy Storage & Catalysis | Custom nanofiber structures engineered to each client's performance specification. |
TruSpin also offers roll-to-roll nanofiber collection, intrafiber additive encapsulation (building a customer's proprietary materials directly into the fiber matrix), and analytical and physical testing services for nanofiber materials.
