Abstract

[en] This project tackles the problem of miniaturizing biomedical sensors by designing a brand new wireless device used to measure vital signs using electrocardiogram and photoplethysmogram signals as well as body temperature. The starting point of this project is wearIT4Health, a similar project conducted by the research laboratory supervising me, Microsys. Adequate electronic components are discussed and chosen permitting the best miniaturization possible. Moreover, electronic schematics are presented and explained as well as the printed circuit board design of 2 prototypes: one without microcontroller, due to the worldwide shortage in integrated circuit availabilities, and one with. Furthermore, the software running the microcontroller on the board it is soldered is presented and described as well as how data is transmitted from the sensors to the microcontroller. After that, the chosen wireless communication protocol, Bluetooth Low Energy, used to transfer data from the microcontroller to the pairing device is explained as well as how data will be collected and displayed on this pairing device, being an Android smartphone. Finally, tests are conducted on both prototypes and some parts of the device are validated: the battery management system, the radio frequency part and the body temperature sensor. This project is thus a proof that biomedical sensing devices, even very recent such as wearIT4Health, can be further miniaturized to improve comfort of the patient and reduce nurses amount of work.
