Improving Perinatal Decision-Making: Development of Complexity-based Dynamical Measures and Novel Acquisition Systems
2010 - 2013
Sponsor: Harvard Medical School - Portugal program, FCT
The work addresses the development of Remote Fetus Monitoring from biosensors, involving medical groups at Harvard and Portugal, two sensing device companies (Omniview Sisporto by Speculum in Portugal, and DynaDX in Taywan), and two groups focusing on applying technologies in biophysics and wireless communications.

The architecture for remote fetus health monitoring comprises two main set of devices: sensing modules and handheld devices, which can be mobile phones or tablets. The mobile device collects sensor data, being responsible for permanent updates to a centralized hospital system. The webserver receives and stores the raw data, processes it and makes it available for both the patient and health care provider sites, offering user interfaces to properly display the data. Furthermore, users (patients and health professionals) can also use the web interface at any given time to visualize the data, with no location restrictions.

The DynaDx device is connected to a MAX232 circuit board, which converts the RS232 signal to a Transistor-Transistor Logic (TTL) signal. This board was connected to an Arduino processing unit, which communicates through a Bluetooth shield, enabling the device to receive and transmit. The system is compact, portable, and solely requires an additional AAA battery, summing up to a total of two AAA batteries per device. All the electronics fits within the original sensor case.
