Flexible EMG Sensors and AI in Tennis: Biomechanics, Stroke Analysis, and Injury Prevention

Digital Transformation of Tennis and the Role of EMG

Racquet sports are entering a new phase of digital transformation. Video analysis and wearable sensors have laid the foundation for performance tracking, but they struggle to capture what happens inside the body: how hard muscles work, when overload appears, and how fatigue builds up.

In 2025–2026, flexible surface EMG (sEMG) sensors become a key missing layer. Integrated with Tennis AI solutions and developments by Inventale, they enable a new category: AI coaching powered by biomechanics and biosignals.

What Are Flexible EMG (sEMG) Sensors?

In this article, flexible EMG sensors refer to next-generation flexible surface electromyography (sEMG) sensors designed for sports and wearable applications. They are ultra‑thin, almost weightless, bendable sensor platforms with soft electrodes that adhere to the skin and reliably record muscle activity even under bending, stretching, and high‑intensity movement.
