面向可穿戴电子的海藻酸钠基力/磁双模响应型传感器的性能研究
Performance Study of Sodium Alginate-Based Force/Magnetic Dual-Mode Responsive Sensors for Wearable Electronics
摘要
Abstract
Wearable flexible sensors are of great significance for people's quality of life and health.Porous structural materials,with their advantages of being lightweight,flexible,and having a fast response speed,hold greater promise in the field of flexible wearable sensors.Therefore,a wearable flexible sensor based on a sandwich porous structure made of sodium alginate(SA)/polyvinyl alcohol(PVA)and polyvinylidene fluoride(PVDF)is proposed.The porous sponge uses SA/PVA as the matrix and incorporates magnetic particles(MPs),forming a porous structure through freeze-drying.To further optimize the mechanical and electrical properties of the SA/PVA porous sponge,piezoelectric polymer material PVDF is introduced,forming a multilayer structure using a double-sided casting method.Repeated mechanical performance and magnetic response performance output tests are conducted on the SA/PVA/PVDF porous sponge to verify its stability,recoverability,and repeatability.Under external stimuli,the cycle number can reach up to 5 000 times,and test results in wearable applications indicate that it has a sensitive response capability.This sample fully utilizes the characteristics of SA and PVA,and the designed multilayer composite structure successfully improves the mechanical performance and sensing performance of the sensor.关键词
