Abstract
  • In this thesis, I report our research work on development of a new generation of Cortical Metrics systems (CM), using the STM32F4 embedded system, and the development and integration of a new heart rate measurement function into the new system. In this thesis, I introduce the background of this project, the hardware system STM32F4 Discovery Board, the compiling environment settings and the software I used. I report the test of proper working conditions for the heart rate sensor---the pulse sensor, the signal processing method for identification of heartbeats from the signal that coming out from the pulse sensor. I discuss the conflicts of arranging recourses on the STM32F4 Discovery board, and present our solution of how to integrate the heart rate module into the tactile stimulator system reasonably, so that different modules of different functions in the tactile system could work independently and effectively. Worked together with Dr. Holden Jameson, we also made the communication between the heart rate module and the computer, and used three different displaying methods for the heart rate module. In sum, we successfully built a new heart rate module, and integrated the heart rate module into the Cortical Metrics system. The new CM system with heart rate measurement has been successfully tested and used by different users. We are looking forward to its further application in scientific research of neuronal diseases and looking for its test with more patients.
