Several studies have addressed these facts and some emerging technologies are capable of monitoring and anticipating these problems. With the advance in the development of smart textiles, it＇s possible to use these technologies in the acquisition of biosignals, which allows obtaining a better comfort regarding the use of smart clothes over traditional Ag/AgCI electrodes. In this way, it is possible to monitor for longer periods reducing the discomfort to the user. This paper reports the development of a low cost sensor with the capability of monitoring the electrical activity of the heart, measuring the heart rate and body temperature and is applied in the scenario： health ＆ wellbeing, targeting the continuous measurement of vital signs.展开更多

Fetal movement is one of critical indicators of fetal monitoring, which plays an important role in fetal health. Counting the number of fetal movement by pregnant women is a traditional method for long-term monitoring. However, there are many defects in pregnant women’s feeling count, which cannot meet the accurate requirements of modern perinatal medicine. With the rapid development of biological and electronic technology, various sensors are used to probe the fetal dynamic monitoring, but not on fetal movement. This research proposes a monitoring method for fetal movement via three electrodes. Briefly: first, three electrodes are used to extract electrical signals in the abdomen of pregnant women;second, these signals are amplified and filtered;third, A/D converter with microprocessor is used to make analog digital conversion, which can be stored in the SD card under the control of the microprocessor;finally, the SD card data are processed by computer software and the fetal movement information is analyzed.展开更多
