Wearable e‐textile and cnt sensor wireless measurement system for real‐time penile erection monitoring

초록

Erection measurements are the most important indicator of male urological disease diag-nosis, treatment, and results. Rigiscan has been used widely in studies and diagnoses for nocturnal penile tumescence for evaluating erectile dysfunction by measuring the number and timing of erectile dysfunctions during sleep. However, this device has limitations such as the weight and bulk of the device and has been questioned for its role as a standard for ED Erectile Dysfunction (ED) diag-nosis. In this study, we propose a real‐time wearable monitoring system that can quantitatively measure the length and circumference of the penis using electronic textiles (E‐textile) and carbon nanotube (CNT) sensors. The E‐textile sensor is used to measure the length, circumference, and gra-dient with portability, convenience, and comfort. Sensors were created by coating CNTs on latex for flexibility. The CNT‐based latex condom‐type sensor in our proposed system shows the length, cir-cumference, and curvature measurements with changes in resistance, and the E‐textile performance shows a 1.44% error rate and a cavity radius of 110 to 300. The results of this conceptual study are for supplementary sensor development with a combination of new technologies with alternatives or existing methods for measuring erection function.
