An integrated wearable self-powered platform for real-time and continuous temperature monitoring

Biocompatible and reliable temperature monitoring platforms are constantly required to develop wearable electronics for future sophisticated health diagnosis and protection of high-risk individuals. Considering the fact that heat exposures during pregnancy might increase the risk for abortions, premature birth or congenital heart defects, here, we propose a conceptual self-powered temperature monitoring platform for simultaneous real-time tracking of the temperature variation in lower limb of a pregnancy woman and her surrounding environment during exercise. Thanks to the special channel design and local spindle-shaped construction, the single yarn -based temperature (SYBT) sensor exhibits ultrahigh sensitivity, bending resistance, good biocompatibility and integrability with fabrics. A vertical contact-separate mode triboelectric nanogenerator embedded into a shoe extracts energy from body motion to power the SYBT sensors, achieving the self-powered features of the plat-form. Coupled with wirelessly date transmitting and user interfaces, the temperatures of pregnant volunteer's lower limb and surrounding ambience are simultaneously and continuously monitored during exercise in a self -powered manner. Such SYBT sensors and self-powered design strategy provides a new avenue for future tem-perature monitoring electronics.

This paper proposes a conceptual self-powered temperature monitoring platform for simultaneous real-time tracking of the temperature variation in the lower limb of a pregnant woman and her surrounding environment. The single yarn-based temperature (SYBT) sensor exhibits ultrahigh sensitivity, bending resistance, biocompatibility, and integrability with fabrics. The triboelectric nanogenerator embedded into a shoe provides energy for the self-powered features of the platform, and the temperatures are continuously monitored wirelessly with user interfaces.
