Abstract
A simple transducer which is based on changes of electrical capacity with volume is described. The system accomodates fluid volumes of several microliters and the resolution is below one nanoliter. The response time of the transducer is about 10 ms. The system is applicable for continuous recording of flow rates in renal collecting tubules. Pulsatile flow in the duct of Bellini is demonstrated.
摘要
描述了一种基于电容随体积变化的简单传感器。该系统可容纳几微升的液体体积，分辨率低于一纳升。传感器的响应时间约为10毫秒。该系统适用于连续记录肾集合小管中的流速。展示了贝氏管中的脉动流。
