Nocturnalyze: Real-Time Sleep Disturbance Therapeutic Device

Sleep disturbances among college students are widespread and linked to adverse mental health and academic outcomes. To address this, we developed Nocturnalyze, an intuitive, non-invasive system that combines real-time sleep monitoring with automated therapy using off-the-shelf sensors. The device integrates a mattress pad with 10 force-sensitive resistors, a microphone, a thermistor, and a hydrometer to detect motion, noise, and environmental disruptions without direct physical contact. When disturbances (e.g., excessive movement or ≥ 60 dB noise) are identified, the system triggers therapeutic interventions: (1) warm yellow light pulses (590 nm) to promote relaxation and (2) algorithmically generated pink noise (100 Hz–8 kHz) to mask disruptive sounds. Initial testing confirmed accurate disturbance detection and timely therapy activation. By leveraging accessible hardware, Nocturnalyze offers a scalable solution to improve sleep quality in students, with future work focusing on human trials, adaptive therapy, and mobile app integration.
