可监测动脉血压波形的超声阵列柔性传感器
Ultrasonic array flexible sensor for monitoring arterial blood pressure waveform
摘要
Abstract
In order to solve the defects of traditional ultrasonic sensors,which are rigid and not easy to skin adhesion,an ultrasonic array flexible sensor is designed and developed.By transferring the"S"shaped stretchy copper foil electrode to the Eco-flex substrate,and then welding 1-3 piezoelectric composite material on the copper foil electrode,and finally packaging with Eco-flex,a flexible stretchy ultrasonic array sensor is prepared.The sta-bility,repeatability,axial resolution and stretchinability of ultrasonic array flexible sensor are studied.The re-sults show that the axial resolution of the ultrasonic array flexible sensor can reach 330 μm,and the elongation at break of the electrode can reach 76.56％,which can still recover the initial state after stretching,twisting and bending.It can continuously monitor human arterial blood pressure waveform,and the error of blood pressure monitoring results is less than 2 mm Hg compared with that of commercial blood pressure monitors.关键词
