Abstract: With the rapid development of portable devices and internet of things, the requirement of system wearability and integration accelerates the investigation of flexible multifunctional sensors. In this study, we developed an integrated flexible sensing system with four nanowire-based sensors and a Ni microwire-based temperature sensor. The four nanowire-based sensors are three kinds of photodetectors responding to lights with different wavelengths and a gas sensor. Due to the large surface volume ratio and considerable sub wavelength effect, all the nanowire-based sensors show good sensing response and excellent linear relationship between sensitivity and temperature. The as-fabricated flexible sensing system can simultaneously detect environmental parameters, including temperature change, light intensities from UV-Visible to near infrared regions, and harmful gas concentration. Our flexible multifunctional sensing system therefore opens up a new way for the emerging portable and wearable electronics.
