用于生物医学信号检测的超薄测力传感器

随着社会文明程度的不断提高和人口老龄化的发展，人体股骨骨折的预防在现代社会中的重要性和巨大社会意义日益引起人们的关注。通过仿真实验研究冲击状态下人体皮下脂肪对冲击能量的吸收和冲击力的衰减机理，可以为骨折防护器的设计提供可靠依据。本文介绍了利用压电薄膜制作的超薄测力传感器在上述实验中的应用、测量原理和和测量系统的构成以及与之相配套的计算机应用软件。

Applications of wafer transducers in measurements of biomedical signals

More and more attention has been paid to the protection from hip-bone fractures especially of the old in our society. Test results have shown that enery absorption and force atte nuation caused by the soft tissue covering the hip-bones have significant meaning in designing and manufacturing protectors against hip- bone fractures. An author -developed wafer transducer together with a computer - aided - testing software was used in the these tests to give out satisfactory results.
