  • Publication number: 20170265799
    Abstract: A fetal movement measuring device includes a wearable article to be worn on a pregnant woman's abdomen, plural measurement units, and a mobile device pre-installed with a fetal movement algorithm. The measurement units are provided separately on the outer surface of the wearable article and each include a fetal movement sensor for sensing a dynamic physiological signal of the abdomen and a power supply element for supplying necessary electricity to the fetal movement sensor. The dynamic physiological signals sensed by the fetal movement sensors are received by the mobile device, processed with the fetal movement algorithm, and rid of synchronous signal components. Then, the fetal movement algorithm performs calculation on the remaining signal components to generate fetal movement information, which includes a fetal movement location and a fetal movement magnitude. Thus, each fetal movement is measured in a non-contact manner, and its location, obtained through asynchronous multipoint measurement.
