“…The Krimholtz, Leedom, and Matthaei (KLM) transmission line model is an equivalent circuit model generally used to determine electrical and mechanical transducer properties [ 23 , 24 ]. The KLM model has the advantage of assuming the acoustic part of the piezoelectric transducer as the transmission line, making it easier to interpret physically and is less time-consuming than finite element analysis (FEA).…”

Accurate measurement of bladder volume is an important tool for evaluating bladder function. In this study, we propose a wearable bladder scanner system that can continuously measure bladder volume in daily life for urinary patients who need urodynamic studies. The system consisted of a 2-D array, which included integrated forward-looking piezoelectric transducers with thin substrates. This study aims to estimate the volume of the bladder using a small number of piezoelectric transducers. A least-squares method was implemented to optimize an ellipsoid in a quadratic surface equation for bladder volume estimation. Ex-vivo experiments of a pig bladder were conducted to validate the proposed system. This work presents the potential of the approach for wearable bladder monitoring, which has similar measurement accuracy compared to the commercial bladder imaging system. The wearable bladder scanner can be improved further as electronic voiding diaries by adding a few more features to the current function.
