AI Rejuvenation Cocoon for Athletes is an intelligent recovery system that performs a therapist-like cycle of sensing, decision-making, physical actuation, and reassessment within one cocoon. At the start of each session, multimodal sensors establish the user's baseline physical and mental condition from heart rate, HRV, respiration, stress, movement, temperature, posture, and contact-pressure data. The AI combines this assessment with the user's selected goal and prior session history to determine the sequence, intensity, timing, and output of 10 recovery modalities. During the session, the system continues monitoring the user's physical and mental state and recalibrates the program every minute, translating measured changes directly into adjustments in massage, heat, light, oxygen, sonic vibration, sound, PEMF, and related outputs. Acting as an AI Personal Physical Therapist, it automates key parts of condition assessment, personalized program generation, coordinated recovery delivery, and progress tracking within one integrated physical system.
