How Digital Twins Enable Real- Czas Fractury Monitoring

Fractura monitoring using digital twins requires adampting thee generic architecture to o thee unique conquilenges of either living bone or structural materials. The process unfolds in several interconnected stages.

Data Acquisition from Sensors

Sensors are te eye ande hears of thee digital twin. For ortopedic applications, smart implants equipped with micro- sensors measure strain, temperature, pressure, and even micro- motion across thee fracture site. Wearable implants andd gyroscopes attached to the limb capture gait paraxns and load distribution during daily actities.
