This paper describes a new technique to measure urine volume in patients with urinary bladder dysfunction. Polypyrrole - an electronically conducting polymer - is chemically deposited on a highly elastic fabric. This fabric, when placed around a phantom bladder, produced a reproducible change in electrical resistance on stretching. The resistance response to stretching is linear in 20%-40% strain variation. This change in resistance is influenced by chemical fabrication conditions. We also demonstrate the dynamic mechanical testing of the patterned polypyrrole on fabric in order to show the feasibility of passive interrogation of the strain sensor for biomedical sensing applications.
本文描述了一种测量膀胱功能障碍患者尿量的新技术。聚吡咯——一种导电聚合物——通过化学方法沉积在高弹性织物上。当这种织物包裹在模拟膀胱周围时，拉伸时会产生可重复的电阻变化。在20%-40%的应变变化范围内，电阻对拉伸的响应呈线性。这种电阻变化受化学制造条件的影响。我们还展示了对织物上图案化聚吡咯的动态力学测试，以证明应变传感器用于生物医学传感应用的被动询问的可行性。
