Based on numerous literatures,the sensing mechanism of the multi-parameter sensor based on PEDOT:PSS-NFC((3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid)-nanocellulose)aerogel was analyzed and the sensor characteristics of the output pressure(P),temperature(T)and humidity(H)completely decoupled by a single device was analyzed,too.It is concluded that the pressure sensing of the multi-parameter sensor of PEDOT:PSS-NFC aerogel comes from the mechanical properties based on the mi⁃crostructure of PEDOT:PSS-NFC aerogel,and the temperature and humidity sensing comes from the thermo⁃electric effect of PEDOT:PSS.This kind of sensor that is completely decoupled by a single device with output pressure(P),temperature(T),and humidity(H)characteristics is expected to solve the current complex multi-parameter electronic strain sensor integrated circuit and multi-parameter output signal crosstalk prob⁃lems,it has high application prospects in distributed diagnosis,electronic skin and wearable devices.
