This article describes a modified and improved version of the displacement transducer design originally presented by Sandeman (1968). The present design generates a high frequency electric field in the bathing solution. Relative displacement is detected within this field by measuring the differential voltage between two small diameter wire-sensing electrodes, which can be attached to different biological structures. By placing one of the sensing electrodes at a fixed point within the bath, absolute displacement can also be measured. A brief theoretical discussion and complete design are presented for the differential displacement transducer. The method presented here is more sensitive and versatile than the original approach.
本文描述了一种对桑德曼（1968年）最初提出的位移传感器设计进行改进后的版本。当前设计在浴液中产生高频电场。通过测量两个小直径线状传感电极之间的差分电压来检测该电场内的相对位移，这两个电极可附着于不同的生物结构。通过将其中一个传感电极置于浴液中的固定点，也可测量绝对位移。文中给出了差分位移传感器的简要理论探讨和完整设计。此处提出的方法比原方法更灵敏、更通用。
