Wearable Acoustic System for Real-Time Prediction and Prevention of Bone Fractures
This invention is a wearable system that continuously monitors bone health using acoustic emission sensors placed directly on a patient's body. By capturing the microscopic crackling noises generated as a bone nears failure, the technology accurately forecasts and alerts the patient before a catastrophic fracture occurs.
Description
The technology operates by detecting acoustic emissions (AE); ultrasonic crackling sounds - that naturally occur within quasi-brittle materials like bone as they experience a progression toward structural failure. The system utilizes one or more wearable AE sensors (such as piezoelectric transducers or microphones) paired with reference sensors placed to minimize background noise. These sensors maintain constant acoustic connection with the bone over a prolonged duration to capture data on cumulative acoustic energy, total events, and amplitude rates in real time. The captured data is evaluated by specialized software algorithms stored in electronic circuitry, such as a connected personal smartphone or a customized processing unit. The system calculates the rate and amplitude of variables, projecting a declining trend line where the inverse AE energy rate approaches zero. This analysis predicts the remaining loading cycles and time to failure under the patient’s typical movement conditions, enabling a dynamic warning system that signals when loading must cease to prevent structural collapse.Applications
- Monitoring bone health in patients with osteoporosis to anticipate fracture risk before clinical symptoms arise.- Assessing bone integrity in cancer patients with metastatic bone disease, where early fracture prediction is critical.
- Supporting post-operative rehabilitation by providing continuous feedback on bone healing status following orthopedic surgeries.
- Use in clinical trials to objectively assess the efficacy of bone-strengthening therapeutics and interventions through non-invasive monitoring.
- Integration into personalized healthcare platforms to enable remote bone health management and reduce hospital visits.
- Providing clinicians with a diagnostic tool for early-stage detection of bone degradation in at-risk populations.
