A transducer has been developed for measuring the minute forces generated during isometric contractions (1.0-10.0 microN) of single smooth muscle cells from the pig urinary bladder and the human uterus. In addition to its high sensitivity, resolution and stability (100 mV microN-1, and less than 0.1 microN and less than 2.0 microN h-1), the transducer features a very wide range (100-140 microN) with good linearity, enabling measurement of contractions as well as passive force-length characteristics within one uninterrupted measurement session. Since the transducer features an independent and interchangeable force to displacement conversion system, different force ranges can be realized by inserting force conversion systems with different compliances.
已经开发出一种传感器，用于测量来自猪膀胱和人类子宫的单个平滑肌细胞在等长收缩（1.0 - 10.0微牛顿）过程中产生的微小力。除了具有高灵敏度、分辨率和稳定性（100毫伏/微牛顿、小于0.1微牛顿和小于2.0微牛顿/小时）外，该传感器还具有非常宽的测量范围（100 - 140微牛顿）和良好的线性度，能够在一次不间断的测量过程中测量收缩以及被动的力-长度特性。由于该传感器具有独立且可互换的力-位移转换系统，通过插入具有不同柔度的力转换系统，可以实现不同的力测量范围。
