In this work, multimodal responsive optical waveguide sensors using a stable cross-linking gel polymer electrolyte are successfully designed and fabricated by bottom metal-printing technology. Temperature humidity sensing characterization based on the is simulated analyzed. The properties of photonic chip defined analysis ion relaxation dynamics: phase variable to monitor temperature attenuation detect humidity. supervising (36.0-38.0 °C) relative (45-65%) range, sensitivities device measured as 0.5π rad/°C 1.14 dB/% RH, respectively. fast-response time for both multifunctional sensor can be obtained 4.21 ms 1.32 s, These findings provide feasible scheme design application in potential medical treatment. From electrolytes multimode monitoring applications, exploration high stability ultrafast response gradually being carried out. This study has great significance comprehensive sophisticated human physical signs sensors.
