The innovative functional design and flexible integration of microelectronic systems are the driving forces behind the advancement of smart wearable devices in the field of proactive health monitoring.This work employs STM32 control processing chips,temperature and humidity sensors,signal collection and wireless transmission modules,as well as optical components like fiber optics,to design and develop a temperature and humidity data visualization monitoring system.Based on ultra-low modulus silicone nonaqueous gel and 3D spacer fabric as the main materials,a stretchable circuit board with intrinsic and structural flexibility was further fabricated to directly integrate and package this system as a waist-wearable belt-type device for visualizing human microenvironment(data)monitoring.The novel silicone nonaqueous gel composite fabric material used has a Young's modulus and bending stiffness of only 0.113 MPa and 114.680 mN·mm,respectively.Not only did it well retain the inherent soft compliance of fabric substrate,effectively introducing the excellent biocompatibility,hydrophobicity,and electrical insulation of silicone materials,but also achieved further enhancement in mechanical properties such as tensile strength and elongation at break,increased by 48.775%and 22.507%,respectively.The resulting human microenvironment visualization monitoring belt underwent wearable simulation testing on a mannequin,successfully achieving real-time detection and monitoring of temperature and humidity variations in the human microenvironment through color changes in the stretchable fiber optic display board.Moreover,this functional belt,allowing mobile monitoring and data storage thorough smart phones and computers,showcases significant potential in specialized care areas,such as daily care for bedridden elderly.
