    "body_text": "A force-sensitive resistor in an abdominal belt connects to a custom Bluetooth Low Energy board and records expansion through a mechanical holder. Signals remained visible across breathing maneuvers, body positions and light movement; in a 12-person stress protocol, the best classifier reached 88.0 percent test accuracy. The experiment is preliminary and does not establish diagnosis, generalization or performance during unrestricted daily activity.",
