摘要
Abstract
This study employs the operating principle of semiconductor-based resistive strain sensors to fabricate an inter-mediate conductive layer using two distinct methods:spatially-confined forced assembly and screen printing.Compara-tive analysis revealed that the sensor produced via spatially-confined forced assembly demonstrated superior suitability for pre-radiotherapy breathing training in patients.Under a maximum applied strain of 24%,the sensor exhibited stable per-formance,with a fitted sensitivity of K=0.0015 V/mm and a repeatability of 96.67%.Tensile testing at 10%strain yielded a rapid response time(Tr≈137 ms),meeting the requirements for real-time monitoring.Forward and reverse stroke output-input curve measurements further revealed a low return error(δH=1.06%),demonstrating the working stability of the sensor during prolonged operation.Finally,respiratory signals were successfully collected from ten indi-viduals with varying chest circumferences,highlighting the clinical utility of the sensor in medical diagnostics and patient-specific respiratory monitoring.关键词
