  "textContent": "An electronic medical device includes a disposable housing and a primary circuit that interacts with external secondary circuits through magnetic coupling. The primary circuit, housed in a sealed, removable unit, includes an inductor and capacitor forming a resonant circuit monitored by a connected circuit that detects electrical characteristics. Positioned near the primary circuit, the secondary circuit contains an electrical actuator with its own resonant circuit. The device operates via mutual inductance between the primary and secondary circuits, with the monitor detecting changes in response based on the actuator's state. A frequency-swept alternating current (AC) signal is used to measure these characteristics, allowing the detection of actuator states. The system can be expanded with additional secondary circuits, enabling further magnetic coupling and monitoring. The device's design facilitates activation and monitoring of multiple actuators through resonant frequency responses for precise control and feedback.",
