How To Design And Build A Penile Sensor Monitoring Nocturnal Erections To Aid In The Diagnosis Of Erectile Dysfunction?

This project explores the development of a wearable sensor system designed to monitor nocturnal penile erections, aiming to aid in the diagnosis of erectile dysfunction. The system integrates multiple sensors, including thermistors, a stretch sensor, a pulse oximeter, and an accelerometer, managed by the Arduino Nano 33 BLE Sense Rev2 microcontroller. The sensors monitor key parameters such as penile temperature, circumference, blood saturation, and movement. Key findings include the identification of the Semitec 203AT-2 thermistor for its precision in capturing temperature changes and the selection of a flexible stretch sensor over a bend sensor due to its reliable performance in monitoring circumference changes. The MAX30102 oximeter was validated for arterial pulse measurement but encountered challenges in accurately measuring blood saturation levels, suggesting the need for further development or alternative solutions. The 3D-printed casing provided a secure and compact housing for the system. Future iterations should address user comfort by incorporating thinner wires and optimizing component integration. The study also highlighted the need for improved data transfer via Bluetooth Low Energy (BLE) and potential enhancements like a user-friendly app and an indicator LED for system status. Overall, the project presents a promising proof-of-concept for a low-cost, effective nocturnal erection monitoring system, with recommendations for future research and development to enhance its functionality and user experience
