Abstract:
We found that a spider-slit-inspired bionic structure is not only sensitive to tiny vibrations but also exhibits remarkable sensitivity to temperature changes, as confirmed through testing. Based on these findings, we propose a bionic, crack-based graphene temperature sensor, whose temperature sensitivity reaches 9.93 × 10-3 °C-1. We studied the influence of the thickness of the PDMS substrate and the laser-scribing angle on the performance of the sensor; the optimized parameter for the thickness of the PDMS substrate is 400 μm, and the laser-scribing angle is θ = 0. Meanwhile, the proposed graphene-based temperature sensor has great clinical potential for the real-time monitoring of human body temperature, and it also can be used for water/liquid temperature-change measurements and food-storage temperature detection.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
