Sports-lab grade biomechanical analysis — delivered to every coach on the court.
SwingFlux is a 4-IMU wearable sensor system that captures 50+ biomechanical parameters in real time. No camera required. Session-ready in minutes. Your coaching instincts, now backed by data — and amplified by AI that knows each player's unique mechanics and improvement history.
As a coach, you know exactly what's wrong with a player's serve or forehand — but until now you've had no way to prove it with data, track it over time, or show players the precise numbers.
Clip on the 4-IMU sensor kit in minutes. Works with any racket, any court. No cameras or lab setup needed.
Real numbers for every shot: elbow angle, shoulder rotation, forearm pronation, racket lag — the full kinetic chain in real time.
Week-by-week biomechanical progress. Show players exactly what's improving — coaching that's impossible to argue with.
From wearing the sleeve to a full biomechanical coaching report — in a single session.
Wear the sleeve, hit your shots. 500Hz sensor data captured automatically.
50+ biomechanical parameters computed instantly across every shot.
Session-over-session trends. PDF reports for players and parents.
AI reads each player's full history across all 50+ parameters and generates precise, personalised coaching instructions — unique to that player, that session.
A wearable sensor kit that captures what coaches can't see, paired with an analytics platform that turns that data into actionable coaching intelligence.
IMU 1 (upper arm) + IMU 2 (forearm). Captures shoulder rotation, elbow extension and forearm pronation.
IMU 3 (handle) + IMU 4 (throat/head). Measures racket speed, impact vibration, lag and whip effect.
Real-time dashboard on phone, tablet and desktop. Shot breakdown, player comparison, AI drill recommendations.
All 4 IMUs sample at 500Hz simultaneously — capturing arm-to-racket lag, impact timing and pronation speed.
IP protection covering hand + racket sensor based biomechanical analysis. Filed in the Netherlands.
Every metric has a direct coaching application. Multi-player dashboard, session reports, academy benchmarking.
SwingFlux doesn't just measure biomechanics — it learns them. After every session, an AI trained on that player's unique 50+ parameter profile analyses their specific weaknesses, improvement trends and response to drills. The result is personalised coaching intelligence that gets more valuable the more it is used.
The AI doesn't give generic coaching tips. It reads that specific player's full biomechanical history — every parameter, every session — and generates instructions that account for their unique strengths, weaknesses and how they respond to specific drills.
Every metric — elbow extension speed, forearm pronation timing, racket lag, trunk rotation, impact consistency — is tracked session over session. The AI identifies which parameters are improving, which are plateauing and which are regressing, and adjusts its recommendations accordingly.
Not a list of observations — actionable instructions. The AI ranks the top 3 things to work on this session, explains why in plain language, and prescribes specific drills with expected impact on measurable parameters. Coaches can hand this directly to a player.
Over time, the AI builds a rich biomechanical profile for every player in your academy. As more player data is collected and the AI is tuned, these personalised coaching models become increasingly precise — and increasingly difficult for any competitor to replicate.
Every AI output is written for coaches, not engineers. Clear summaries, plain English drill prescriptions, and trend charts that make sense at a glance — even for coaches with no data background.
Maria's core transfer efficiency has dropped for the 2nd consecutive session (now −19% below benchmark) despite strong racket-head speed gains. Historical data shows this pattern appeared in sessions 6–8 and was resolved by hip-lead sequencing work. The current swing plane inconsistency (±6° variance, worsening) is a symptom of the same issue — she is initiating trunk rotation before the hip drive is complete.
Priority 1: Hip-lead shadow swings — 3 sets × 15 reps, focus on hip clearing before shoulder unwind. Expected impact: +8–12% core transfer within 3 sessions based on Maria's Session 7–9 response data.
SwingFlux measures what the human eye simply cannot. Every shot type broken down into 8 specific biomechanical metrics, plus a cross-cutting impact quality layer.
