Abstract
A fetal heart sound transducer and an uterine contraction monitor transducer are designed utilizing an extended PVDF-film with the transverse effect due to d 31 constant and silicone rubber. A receiving and a transmitting part of array are fabricated on the film constructing the transducer so that the frequency response of the transducer on abdominal wall can be detected for each patient. The useful clinical data on fetal heart sound and the frequency spectrum have been obtained and uterine contraction monitoring is performed.Keywords
