Abstract:Fetal movement is a significant indication of fetal well-being. Standard clinical fetal monitoring technologies include ultrasound imaging and cardiotocography. Both have limited prognostic value and require many health resources. We have recently developed a low-cost, passive, non-invasive and portable system based on MEMS accelerometer to monitor fetal activity, and therefore fetal health. Using this system, we aim at developing signal processing methods to automatically detect and quantitatively characterize fetal movements. From the paper the conclusion can be reached as follows: The suitability and the efficacy of using MEMS accelerometer to detect the fetal movement is proved; The method mentioned above implements the MEMS inertial sensors to the biomedical areas, and it could be developed as a portable long-term home monitoring device, also as monitoring workstation in hospitals.
