Highly Sensitive, Ultrastretchable, and Degradable PCT-CNT Strain Sensor for Continuous Monitoring of Male Erectile Dysfunction

Abstract

Male erectile dysfunction (ED) has been attracting significant attention due to its serious effect on emotional damage, heavy psychological blow, and life quality. Nevertheless, it is still a challenge to score and monitor ED more conveniently, comfortably, and in real-time with ease at home. Herein, a highly sensitive strain poly (CL-co-TOSUO) (PCT)-carbon nanotube (CNT) sensor with ultrastretchable and degradable ability was designed and fabricated. The proposed PCT-CNT exhibited excellent mechanical properties, its strain can reach up to 2368%, and its tensile strength is over 12 MPa. A fast degradation rate of the PCT-CNT could also be acquired, completely degrading in 8 h in a tetrahydrofuran solution at room temperature. It is worth emphasizing that the proposed PCT-CNT could be assembled as a wearable flexible sensor with practical application potential in male ED detection, which has an excellent signal response with the bending and stretching of the simulated module.
