Sine Health is a wearable system developed for my final major project at Brunel University. It helps emergency service workers regulate their breathing under stress using discreet haptic feedback. By guiding users toward their optimal breathing rate, the device improves heart rate variability - a key marker of resilience and recovery. The project combined user research with police officers, prototyping of multi-motor haptic arrays, and testing of biofeedback methods to create a practical tool for high-pressure environments.
