How to Make a Glove Alarm That Activates When Fingers Touch Palm for Hand Cramp Detection

The discussion focuses on designing a glove-based alarm system to detect hand cramps by triggering an alert when fingers touch the palm. Proposed solutions include integrating metal contacts or copper mesh on fingertips and palm to close an electrical circuit upon contact, activating an alarm. Capacitive sensors are mentioned as a more professional but complex alternative. Small mechanical switches or buttons are considered, but their required activation force may be unsuitable given the strong cramps. Flexiforce sensors are suggested as a practical option; these force-sensitive resistors can be attached to the palm, requiring minimal wiring and providing better usability during normal hand movements. The system would involve conditioning electronics such as op amps, a battery, and a piezo buzzer, potentially housed on a belt. MEMS components are also referenced as possible sensor elements. The cramping involves finger joints locking in a strong grip, which influences sensor choice and calibration. The discussion includes considerations for sensor placement, wiring, and alarm activation mechanisms.
