生物组织的电学性质 ,是我们认识生命物质的一个重要方面 ,对了解生命具有重要意义。但是 ,不同于非生命物质的测量 ,对生命物质的测量必须设计专门的测试电路仪器。为了更全面的了解体液及生物组织的交流频率特性 ,设计制作了一套更加符合对生命物质电特性测试的系统。系统采用了先进的测量方法、最新的专业电路和器件、以单片机为核心的测量控制、数据采集处理系统 ,使系统具有较宽的频率测量范围、阻抗测量范围、较高的测量精度和可靠性、较宽的测量适用对象、以及更智能化。另外 ,系统设计中还充分考虑了电测经生命物质带来的测量影响、在体 (invivo)和离体 (invitro)测量的时间影响等。系统在实际测量中获得了很好的实验结果 ,为生物组织电学性质的研究提供了一种更合理、更准确、更全面的手段。
The electrical nature of biological tissue is an important aspect of our understanding of life’s material and is of great importance for our understanding of life. However, unlike the measurement of non-living substances, the measurement of living substances must be designed to test the circuit equipment. In order to comprehensively understand the frequency characteristics of the exchange between body fluid and biological tissue, a set of system that is more in line with the test of the electrical properties of living material has been designed and manufactured. System uses advanced measurement methods, the latest professional circuits and devices to the microcontroller as the core of the measurement control, data acquisition and processing system, the system has a wide range of frequency measurement, impedance measurement range, high measurement accuracy and reliability , A wider range of measurement targets, and more intelligent. In addition, the system design also fully takes into account the impact of electrical measurement of life substances brought by the measurement, the invivo and in vitro (invitro) measurement time. The system obtains good experimental results in the actual measurement, which provides a more reasonable, accurate and comprehensive means for the study of the electrical properties of biological tissues.
