Abstract:
The integration of multi-functional and flexible wearable sensors is crucial for the development of comprehensive wearable electronic platforms. However, there is still much room for improvement in terms of response time and the accuracy of temperature detection. Here, a multifunctional wearable sensor has been developed, utilizing a composite film of reduced graphene oxide/thermoplastic polyurethane (rGO/TPU) prepared through electrospinning and vacuum filtration. In terms of temperature detection, the sensor exhibits remarkable accuracy of 0.1°C within the range of 36.5°C-42°C, meeting the precise requirements for human body temperature monitoring. Regarding the response to pressure, this sensor has a sensitivity of up to 12.3 kPa-1 within the range of 0-20 kPa. After coating the surface of the rGO/TPU composite film with a layer of fluorocarbon material coating (Fluere-1706Y), the sensor was endowed with remarkable self-cleaning capabilities. This multi-functional sensor provides a comprehensive wearable electronic platform.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
