生物滤波器的等效电路模型

Equivalent Circuit Model of Biofilter

摘要: 本文通过研究鸟类羽毛的耦合结构，构建并推导出：鸟类活体羽毛的“n字型”微观耦合结构与电子电路之间的耦合电路的一种新型等效电路模型。该等效电路模型是由无数个相邻羽枝(等效电感L)与羽小枝(等效电容C)组成的“n”字型结构，等效为无数个LC并联回路，构建出了由羽枝与羽小枝组成滤波器的微基本单元，使其具有生物微型滤波器功能。这些研究成果为研发低频率生物滤波器(截止频率f = 1 Hz, 100 Hz, 1 kHz)提供了理论依据，弥补了低频生物滤波器的研究领域空白。

Abstract: This paper constructs an equivalent circuit model of feathers by studying the coupling structure of bird feathers. A new equivalent circuit model of the coupling circuit between the “n” shaped micro-coupling structure of bird feathers and the electronic circuit is constructed and derived. The equivalent circuit model is an “n” shaped structure composed of an infinite number of adjacent pinnacles (equivalent inductance L) and pinnacles (equivalent capacitance C), which is equivalent to an infinite number of LC parallel circuits. The micro basic unit of the filter composed of pinnacles and pinnacles is constructed, so that it has the function of biological micro filter. These research results provide a theoretical basis for the research and development of low-frequency biological filters (cutoff frequency f = 1 Hz, 100 Hz, 1 kHz), filling the gap in the research field of low-frequency biological filters.
