摘要
The flexible and stretchable multifunctional sensors for the precise monitoring of the human physiological health indicators is an emerging requirement of next-generation electronics.However,the integration of multifunctional sensors into a common substrate for simultaneous detection of such signals without interfering with each other is the most challenging work.Here,we propose MXene-Ti_(3)C_(2)T_(x) and 3,4-ethylene dioxythiophene(EDOT)deposited on laser-induced graphene(LIG/MXene-Ti_(3)C_(2)T_(x)@EDOT)composite-based flexible and stretchable multifunctional sensors for strain,temperature,and electrocardiogram(ECG)monitoring.In-situ electrophoretic deposition(EPD)of MXene-Ti_(3)C_(2)T_(x)@EDOT composite into LIG outperforms high strain sensitivity of 2,075,temperature coefficient of resistance(TCR)of 0.86%,and low skin-contact impedance.The sensor platform is integrated into an ultrathin and highly resilient polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene(SEBS).Finally,we demonstrate onsite detection of human body-induced deformations and physiological health indicators,such as temperature and ECG.The proposed approach paves a promising route to future wearables for smart skin and healthcare applications.
