Application of flexible liquid metal sensor in dynamic load monitoring
Aiming at the strain measurement issues of flexible materials and complex surfaces,a flexible sensor based on microtubules made of high polymer materials was presented.Through a series of calibration experiments and structural design,the real-time monitoring of the strain state of the umbrella coat under different tension loads,human pulse waves and bolt loosening under vibration conditions was achieved.The results show that,benefiting from the high sensitivity and conformity of the flexible micro-tube sensor,the signals collected by the sensor can reflect the strain of the material under dynamic load,and provide new solutions for the strain measurement of flexible material under tensile load,real-time monitoring of human physiological signals,and monitoring of the loosening of parts such as bolts.
