NOVELTY - Preparing strain-temperature dual-response flexible electronic sensor composite material involves mixing the graphene oxide solution and the poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) solution, and ultrasonically mixing them in an ice water bath, and adding vitamin C to reduce graphene oxide, continue ultrasonic mixing, and then sealing and keeping to obtain a hydrogel. The hydrogel is rapidly frozen in liquid nitrogen, and dried in a freeze dryer under vacuum to prepare a composite graphene and PEDOT:PSS aerogel. The mixture of the polydimethylsiloxane precursor and the curing agent is injected into the aerogel to be cured to obtain a strain-temperature dual-response flexible electronic sensor composite material. USE - Method for preparing strain-temperature dual-response flexible electronic sensor composite material for monitoring strain signals and/or temperature signals (Claimed). ADVANTAGE - The strain-temperature dual-response flexible electronic sensor has the characteristics of high sensitivity to temperature, high stretchability and high stability, and single electronic sensor can distinguish both strain and temperature signals at the same time, satisfying its use as a wearable electronic device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for obtaining the sensitivity of the strain-temperature dual response flexible electronic sensor composite material, which involves measuring the impedance value of the electronic sensor at different frequencies, obtaining the impedance value-frequency curve under different strain and temperature conditions, and obtaining the relationship between the impedance value change and the applied strain and temperature change value at the measurement frequency.
