- Wireless Flex Sensor Belt Networks for Foetal Movement Monitoring in Low Risk PregnanciesPublication . Borges, Luís M.; Barroca, Norberto; Zamith, Fernando; Lebres, António SérgioIn this work two flex sensor belts were produced to count the foetal movements in the last four weeks of pregnancy. While one is a standalone solution the other is a wireless flex sensor belt network one. A description of the type of sensors is followed by the discussion of the different types of acquisition and data treatment methodologies. The application to display the deformation angles is presented as well. The wireless sensor network solution is based on the IEEE 802.15.4 standard, and the hierarchical wireless network solutions include a Wi-Fi layer. Preliminary results highlight the need for accounting for mother respiration movements and actual experiences with pregnant woman will facilitate tuning the threshold-trigger, to improve the detection performance.
- Overview of Progress in Smart-Clothing for Health Monitoring and Sport ApplicationsPublication . Borges, Luís M.; Rente, Andreia; Velez, Fernando José; Salvado, Luísa R.; Lebres, António S.Smart-Clothing is a project that combines research in textiles materials and wireless sensor and actuator networks in the context of human body monitoring with statistical methods for the data analysis and treatment. This project aims mainly to aid in the monitoring of the foetal movement in the last four weeks of pregnancy. Besides the integration of sensors in the garment there will be needed a hierarchical communication system that allows the delivery of the data collected from the garment that the pregnant is wearing to the doctor. The pregnant can be either at home or in the hospital. In the first stage of the project tests are being made using several types of sensors integrated in a belt in order to choose the one that is more reliable for the detection of foetal movement. Another sensing task is the manufacture of the electrodes for the electrocardiogram (ECG) system. At this point, the electrodes for the ECG are already made and working. The testing of the sensor for the detection of foetal movement is still being done.
